Introduced modular pistol MastePiece Arms MPA30DMG

The vast majority of models of small weapons created for the use of a specific ammunition. However, some rifles, machine guns or pistols are available in several versions for different cartridge. A rather rare solution is the use of a modular weapon architecture, which allows for relatively quick and easy re-equipping of weapons with other barrels and bolts. A new weapon of this design was recently introduced by the American company MasterPiece Arms. Allegedly, after replacing some parts, the new MPA30DMG pistol can use four types of cartridges.



MasterPiece Arms manufactures various types of small arms for the civilian market. Its product range includes rifles, carbines, pistols and various spare parts. The new MPA30DMG pistol complements the existing range of pistols and is an evolution of the MPA30SST model. At the same time, it is claimed, the new weapon should become the first representative of the new series built on the modular principle - DMG (Defender, Machined, Grip). Thus, on the basis of existing developments, a new type of weapon was created.

The basic version of the MPA30DMG pistol is equipped with an 9 mm caliber barrel and is intended for use of 9x19 mm Parabellum cartridges. In the future, sets will be on sale for retooling the pistol for 5,7x28 mm, .40 SW and .357 SIG cartridges. Due to this, a potential buyer will be able to purchase an 9-mm pistol and, if necessary, retool it in accordance with their needs and desires.

Externally, MPA30DMG is similar to some submachine guns, but it is a pistol that can fire only with single shots. As for the specific look and layout, they are a feature of all MasterPiece Arms self-loading pistols. One consequence of this layout was the large weight of the weapon - more than 1,6 kg. This is significantly more than other modern self-loading pistols.

All the main units of the MPA30DMG pistol are located in a rectangular receiver. In the middle part there is a pistol grip with a trigger guard. According to the layout and ergonomics, the pistol resembles some submachine guns, in connection with which the magazine is placed in the shaft inside the handle. On the right side of the receiver there is a window for ejection of shells. On the left side there is a slit grip bolt.

The modular pistol in the basic configuration is equipped with a rifled barrel with an 5,5 inch length (13,97 mm). In the published photos, the MPA30DMG pistol is equipped with a silencer. Like a number of other weapons by MasterPiece Arms, the modular pistol has automatics based on a free gate. A relatively large and heavy bolt is associated with a return spring located at the rear of the receiver.

The MPA30DMG pistol trigger mechanism only allows single shots to fire. There is a fuse blocking mechanisms. His flag is on the right surface of the receiver above the trigger.

The gun has its own open sight with the ability to customize. The front sight and rear sight are located on the top cover of the receiver. If desired, the shooter can use the MPA30DMG gun with any other sighting device. To install it on the cover has a Picatinny rail. A small bar is also available on the bottom surface of the receiver in the front part. This bar can be used to install a laser pointer, flashlight or any other compatible equipment.

The new modular pistol in the basic configuration is equipped with a magazine for cartridges 9x19 mm, borrowed from Glock pistols. Shops are placed in the receiving shaft inside the pistol grip. The latter is said to have a “fully mechanized aluminum” (fully machined aluminum pistol grip) design. The gun is equipped with an ergonomically shaped handle that provides great ease of use. What exactly is meant by the words "fully mechanized" is not specified.

Now customers of MasterPiece Arms can purchase only the basic version of the MPA30DMG pistol using 9x19 mm cartridges. In the foreseeable future, it is planned to submit kits for re-equipment of weapons for the use of other ammunition. The composition of such kits will include the barrel, bolt and shops, designed for use with a particular cartridge. By replacing these parts, the gun can use the 5,7x28 mm, .40 SW, and .357 SIG cartridges. According to some reports, a kit will be created in the future for using .45 ACP cartridges.

The MPA30DMG modular pistol is delivered to customers in a plastic case. The gun itself, one standard magazine for 9x19 cartridges and a number of other “accessories” are included in the package of delivery. Buyers are offered guns in four colors, from metal to terracotta. The recommended price for a pistol is 679,99 US dollars.

Replacement parts kits are not yet sold. Nevertheless, the company MasterPiece Arms sells some spare parts for weapons that allow you to submit an approximate price order for such kits. So, barrels for 5,7 caliber mm pistols or mm 9 8 inches long are 99,99 dollars. Thus, the cost of a complete set of a pistol and several sets of spare parts can pass through 1000-1200 dollars.

Like a number of other weapons of the MasterPiece Arms company, the modular pistol has automation based on the free shutter ... One of the consequences of this arrangement was the large weight of the weapon - more than 1,6 kg. This is significantly more than other modern self-loading pistols.

More than "tangible" For example, a Glock-22 caliber .40 S&W weighs 650 gr.
The MPA30DMG pistol is a typical representative of the family of so-called "assault pistols" - which in my opinion are a dead-end branch of the development of short-barreled weapons.

You are absolutely right Moreover, previously unsuccessful attempts to release and manufacture "assault pistols" have already been made. So in the late 80s in the United States, the Goncz Armament Inc company produced the Goncz GA-9 "pistol", belonging to the rather dubious, not to say - useless category of the so-called "assault" pistols. With dimensions and weight comparable to submachine guns of the Mini-UZI type, the Goncz GA-9 assault pistol did not have a stock and the ability to fire in bursts. Significant dimensions and weight seriously made it difficult to carry, and the massive free breechblock increased the perceived recoil and vibration of the weapon during high-speed fire, making aiming difficult.

I don’t quite understand what are the advantages of modularity for the user? For the manufacturer - it is clear - no need to develop a new CD every time, etc. And for the user (military)? the transition from cartridge to cartridge - this is such a process in which the replacement of weapons - God forbid, 20 percent of the cost is ....

For the military, the main restraining factor is the range of ammunition available, especially for pistols. Do ministries of defense want to adopt at the same time 5,7x28 mm, .40 SW and .357 SIG in addition to the already used 9 mm Steam? For special. units, the purchase of different cartridges is possible, but here you are right, it is probably cheaper to purchase individual barrels for each type of cartridges.

Yes, and one more thing - with a cartridge of 5,7x28 mm everything is clear, it has an increased breakdown effect relative to a standard 9 mm steam. And why do we need an option with 40 SW and .357 SIG. Isn’t it easier to compare 9mm pair, 40 SW and .357 SIG, choose the best from 3 rounds and use it?

And why do we need an option with 40 SW and .357 SIG. Isn’t it easier to compare 9mm pair, 40 SW and .357 SIG, choose the best from 3 rounds and use it?

The .40 SW is a very popular cartridge in the USA, it is only slightly inferior to the .45 ACP in stopping power, with the smaller size of the cartridge and the ability to use this cartridge in weapons of a more compact size than in weapons under the cartridge .45 ACP. Under this cartridge released a sea of ​​police and civilian weapons in the United States.

The .357 SIG is re-compressed to a smaller .40 SW caliber, requiring only a barrel and magazine change on a standard .40 SW pistol. The .357 SIG is considered a "barrel burner", but is prized among police officers for its penetrating power - it is good against criminals protected by body armor and shooting, for example, through a door. Although, in stopping action, it is slightly inferior to the .40 SW.

9X19 mm Parabellum is a weaker stopping power cartridge. This cartridge is popular primarily in Europe. In the US, traditionally prefer more powerful cartridges.

There is a typo in the photo: ".327 SIG" is .357 SIG:

[bazilio]

Comrade Major, the difference in ammunition in stopping and punching action is insignificant and can be variable. which makes it difficult to simply apply bullets of different types to one cartridge - AP, FMJ, JSP / JHP SJHP and so on. One cartridge with different types of bullets is probably better than several types of cartridges for different tasks

Look at comparisons of stopping action, penetration and external ballistics of different calibers and bullets - such comparisons are made in the USA. If the difference was negligible, then no one would bother with the creation of new calibers and bullets. The range of bullets further expands the scope of the cartridge. The most successful ones become popular and are adopted by specials. services and the police. In the US there is a free arms market that helps to conduct a "natural overview" of new calibers, bullets, and weapons under them.

In the army, excessive "multi-caliber" is undesirable, as it complicates logistics. There are smaller calibers.

To date, the number of different pistol and revolving calibers is significant:

[luiswoo]

9X19 mm Parabellum is a weaker stopping power cartridge. This cartridge is popular primarily in Europe. In the US, traditionally prefer more powerful cartridges.

Well, firstly, for 9x19, stopping bullets appeared comparable to .40S & W.
Secondly, just in the states sra4 9mm vs .40 vs .45 is quite active. The rollers where the pieces of gelatin, meat and clay are selflessly shot, comparing the wound cavities, are completely full. According to the results of .40 and .45, the gauges look rather pale. Having a slight advantage in damage to 9x19, they have stronger recoil and can be taken in less quantity.
Although, the best stopping action from pistol cartridges is .357 Magnum (9x33 mm) with a shot bullet. As shown by a not too "humane" experiment to shoot some mountain sheep, whose body weight was comparable to that of a human.
In general, if you remember that this is a miracle for the civilian market, then most likely it will not "take off". 5,7 × 28 roads, .357 SIG and .40S & W, apart from increasing the penetrating effect, do not give anything special to the pistol, but you will have to put up with increased recoil and fewer cartridges.

[Major_Vortex]

Quote: luiswoo

Continue to reason logically: new 9-mm bullets have appeared, respectively, similar .40 and .45 calibers have appeared, the effectiveness of which is even higher. Right?

And do not confuse smoothbore weapons with rifled. A rifled weapon under a bullet with other characteristics: mass, length of the bullet, its diameter, initial velocity of the bullet and its ballistic coefficient, requires a barrel with a different pitch rifling, at least even within the same caliber. Otherwise, the stability of the bullet in flight is lost and, accordingly, the accuracy of the hit. Also, depending on these characteristics, the ballistic trajectory of the bullet’s flight and its energy changes, which affects the range and accuracy of the aimed shot and the damaging effect of the bullet. The diameter and energy of the bullet affect the stopping effect of the bullet.

In addition to the design of the bullet itself, there are other important characteristics that cannot be neglected. And weapons and ammunition developers are familiar with this problem. Therefore, different calibers are produced in order to cover the shortcomings of one caliber with another.

The .40 SW cartridge is approximately halfway between the .45 ACP and the 9 mm Para, and is very popular in the arms market. About .357 SIG, with a bottle-shaped sleeve, I wrote above.

The main advantage of the 9 mm Para over the .357 SIG, .40 SW and .45 ACP calibers is its compactness and compactness of a weapon designed specifically for this cartridge. But, for example, in terms of stopping effect, the 9 mm Para cartridge is considered insufficient in the USA, in contrast to the popular .45 ACP. He will lose to the .357 SIG cartridge, first of all, in terms of penetration. And the .40 SW cartridge is the golden mean.

Who would talk about it

gross kaput, when will you start your education, instead of pointless trolling on the site?

You do not understand the physical foundations of the flight of a bullet fired from a rifled weapon, which you showed last time when communicating with me. For you, all bullets fly the same. Like: he threw more gunpowder into the chamber and shot away ... - everything is like in the good old days of black powder and cannonballs. Are you an "artilleryman"?

In fact, everything is "a little" more complicated. To ensure the stable flight of the bullet in flight, when calculating the ammunition, the following are taken into account: bullet mass, bullet diameter, bullet length, initial bullet velocity, bullet ballistic coefficient, sleeve shape and volume, quantity and grade of gunpowder, barrel rifling pitch for a given ammunition, estimated barrel length - these values ​​are directly related to each other and affect each other, have certain recommendations and restrictions. Bullet flight is ultimately influenced even by ambient temperature and altitude.
Bullet diameter, weight, length, ballistic coefficient and muzzle velocity affect the bullet's "flight" characteristics. For example, a small and light bullet quickly loses speed, and a bullet with low ballistic coefficients is inferior to a better quality one in flight range, trajectory steepness, accuracy and wind drift.

Now compare such a bullet with a fraction of a shot in a short barrel of a pistol / revolver? If you shoot at close range, then the fraction may well be nothing. And then 10 meters I'm not sure that the pellets will have sufficient accuracy. Yes, and energy, and hence slaughter, they will lose much earlier than a large solid and heavy bullet. With a rainproof bullet, a similar picture.

Are you sure after that that all bullets are the same and everything is decided only by the charge of gunpowder in the barrel?

Are you ready to argue about the diameter and energy of the bullet affecting the lethality, or again - "just to talk"?

The fact that you think that the glaser safety slug is a direct analogue of a shot hunting cartridge once again shows how much you are in the topic - specifically brought to you its type - JPF - shell prefragmented bullet - I will explain specifically for you - this bullet DOES NOT shoot shot - the shot is inside bullets - or rather, inside its shell and before it hits the carcass, it flies like an ordinary pistol bullet, but when it gets into the carcass its effect is comparable to expansive only much higher, so it’s better to litter people with your own incompetence; better learn the materiel.

The people above have expressed doubt that it makes sense to use 3 different calibers (9mm pair, 40 SW and .357 SIG) and isn’t it easier to replace them with one, but under bullets with different characteristics that (bullets) cover all three calibers in terms of capabilities?

I just wrote what justifies the use of different calibers today, instead of one. And with one caliber, but for different bullets, it still doesn’t work to completely block all three. Which, however, is confirmed by practice.

Well, I "picked up vershoks in the style of Pop.Mekha" climbed onto the site of hunting ammunition of a very serious and reputable company in the field and chose a super-duper cartridge, which I had never used before, loaded it into the weapon I had shot earlier, I stream .. and he does not fly at the target, "bastard"! And the old cartridges just hit the target.

Explain what I am doing wrong? I am a lamer, and I do not know what to do: the money has been paid, the cartridges are beautiful, on the poster from the website the manufacturer promises super-duper destructiveness and super-duper accuracy, and even draws beautiful graphics confirming his (the manufacturer's) correctness. And numerous hunters who bought these cartridges happily report on the wounded carcasses of deer, kobanchiks and bears, posting photographs of their trophies as confirmation ... That is, divorce on the part of the manufacturer is excluded. Caliber "30-06" ...

It is not correct, it would be more accurate to say that this is far from an axiom and not always a new bullet, even in the same caliber (diameter) but chambered for a different cartridge, why will it be more effective? look for the answer from Fakler. And by the way, apart from the fact that often, due to the design of the bullet itself, it is impossible to use it not in "your" cartridge.

Now, with regard to the lethality of the diameter and energy, the example with .357 magnum and .44 magnum I already cited - I will ask again - according to Marshall and Snow (based on their work on official statistics on the use of weapons), the coefficient of "lethality" of bullets of caliber .44 magnum turned out to be lower than the bullet ratio .357 magnum is 96% and 90%, respectively, although 44 seems to be more caliber and the energy is also higher, you ask, but what about the energy and diameter - and just study the previously listed comrades at your leisure - you will discover a lot of new things for yourself.

Sometimes it’s better to turn on the back to figure out what the thread is about.

You constantly translate the topic into the field of wound ballistics, but at the same time neglect the external and internal.

And, roughly speaking, everything is not limited to wound ballistics, that is, a bullet flies according to physical laws that cannot be neglected. Otherwise, it will fly very badly and most likely not where it should be, and things will not come to wound ballistics at all. Sorry for the pun.

With my example with a hunting cartridge figured out why the bullets do not fly at the target?

What kind of habit do you have - all the time spreading thoughts on the tree? the dispute seems to have begun because of the ODP of pistol cartridges and their bullets, and with regard to civilian-police purposes - and no matter how it touched external ballistics, rifle cartridges, etc. - here let’s end with this, and 30-06, BC, the hunt and we will leave sniper shooting from a pistol on a topic more suitable for this.
As I understand it, you haven't seen the materials of the previously voiced authors? It's a pity, a small problem - we have two cartridges - let it be a 9mm pair and a .357 ZIG, the cartridges are equipped with single-sided shell expansions - let this be the Rem Golden Saber HPJ, when firing at gelatin, the Parabelum bullet passed 30 cm and .357 45 cm - a question Which of them has more CCT? the correct answer is that they are equal - since the width and "thickness" of the average torso, taking into account the need to break through an additional obstacle (hand, tight clothing, just fat) is considered equal to 30 cm, as a result, in a real situation of use on a person, both bullets will transmit the same the amount of energy of the target and will damage the same amount of tissue, only the Parabelum one will fall after the release of a .357 will fly further (and it is not yet known where or to whom). Now that with regards to the caliber (diameter) of the bullet - if such a conversation is still appropriate for the FMJ, and then perhaps only for the "extreme" calibers of the 7,65-45 type, then for civil-police cartridges using mainly expansion and other bullets of increased lethality the difference is the diameter of the opened bullet and the volume of the affected tissues is extremely insignificant, and this insignificance is fully confirmed by statistics.
the example with magnums was not given in vain, it was taken from statistics on the use of weapons by the FBI police and other all kinds of "service people", Marshall and Snow include in their statistics cases when only one shot in the torso was made to hit a target (data on "slaughter places - neck and head are not taken into account) and, accordingly, if the target stopped active actions, then the cartridge / bullets were set plus no minus, as a result, the information was summed up and the efficiency was displayed as a percentage, well, all the most common calibers from 9 mm steam to .44 magnum have from 90 to 95% efficiency and these single percentages of the "difference" are not an indicator of "not much greater efficiency" but quite natural accidents in real life. And here the recommendations to the FBI and police officers are very indicative - regardless of the caliber of the weapon and the type of bullet to continue firing to complete confidence that the threat has been neutralized, and on this basis, in the same recommendations, it is considered the most optimal for police weapons or FBI pistols not with a large caliber but with a large magazine capacity.

This means you don’t know why the bullets fly “wrong”, or you don’t want to answer, because the correct answer will justify the reason for the appearance of ammunition of different calibers, including, with which you critically “disagree” relying only on wound ballistics. I understood why we had a discrepancy ...
About BC. Ballistic coefficient is a new term for you with the meaning of which you came across while discussing the 6,5 Grendel cartridge. I remember. Here I mentioned it, along with other parameters that affect the external ballistics of the bullet, regardless of its type and caliber. And in advanced methods for calculating the BC of a bullet, it is also taken into account when calculating the gyroscopic stability coefficient (SG), the value of which determines the generally stable flight of a bullet fired from a rifled weapon. You didn’t know that either, I’m sure of that.

Quote: gross kaput

As I understand it, the materials of previously voiced authors, you still have not watched? It’s unfortunate that it’s a small task - we have two cartridges - let it be 9mm pair and .357 SIG ...

About the .357 SIG cartridge, I wrote above, what is actually its chip. You skipped it. Incidentally, it is developed on the basis of the cartridge case .40 S&W. The development goal of the .357 SIG was to provide stopping and penetrating action for the pistol cartridge at the level of the .357 Magnum high-power turret ammunition when used in automatic pistols. Due to its high accuracy and good stopping power, this cartridge is used by a number of police departments. Also known as 9 × 22 mm.
The "progenitor" itself - the .40 S&W cartridge was developed at one time as the most practical of the powerful pistol cartridges with a large stopping bullet effect and is a good alternative to the legendary .45 ACP. The main goal of the makers of the cartridge was to combine such qualities as high accuracy and large magazine capacity with acceptable grip thickness provided by the 9mm Parabellum cartridge, and the high stopping power of the .45 ACP cartridge.
The immediate reason for starting work on the creation of this cartridge was the incident when, in a shootout in Miami, two FBI officers died due to the insufficient power of their regular pistols and revolvers under a 9-mm cartridge: when detaining suspected robberies, shooting started in which one of the criminals received multiple penetrating wounds, from which he later died, however, during the shootout, these wounds did not prevent him from firing his weapons and killing FBI agents.
The 0,40-inch (10,16 mm) gauge was proposed by one of the FBI employees who owned their own weapons under the 10 mm Auto cartridge. This employee suggested reducing the power of the 10 mm Auto cartridge, which was too high and had an extremely negative effect on the accuracy of shooting. Sleeve 10 mm Auto, just shortened from 25,2 to 21,6 mm ...
This cartridge has become one of the most popular in the USA. Pistols of the 40th caliber are in service with the police, the FBI and other US law enforcement agencies.
Both cartridges, .40 S&W and .357 SIG - new, appeared approximately in the early to mid-90s.

[Major_Vortex]

.... We continue. Today there is a couple of minutes for a thoughtful study of what you wrote to me here
No wonder I suggested that you discuss hunting cartridges and bullets. On the hunting cartridges, the slaughter of a bullet, its stopping effect and such a concept as the depth of penetration of a bullet have long been run in for a long time. Your complaints regarding:

Taylor's theory in its purest form - it was only popular in the states about 30 years ago, since that time a lot of water has flowed, and at the moment its famous formula at one time is really bad ...

Quote: gross kaput

... argue that if all of your knowledge is enough for understanding the theory of Taylor, for a start, study at least the work of Marshall and Snow, Fakler, reports of the FBI weapons commission ...

Quote: gross kaput

PS Maybe for one thing and explain to me, great gurus, why this is interesting in the works of Marshall and C know ...

... etc.
They only lead me to questions: where did you get these tops from and why do you have such a mess in your head? Wikipedia again played at your leisure?
The influence of the diameter and energy of a bullet on the lethality and RBT has never been refuted by anyone. What "bad manners" are you writing about? Your example about:

Quote: gross kaput

... when shooting at gelatin, the Parabelum bullet passed 30 cm and .357 45 cm ...

It only says that the bullet passed through the body and took part of its energy further, since the penetration depth is excessive - the bullet passed through the body right through. All this has long been known and has been run around many times on hunting cartridges and bullets.
Limitations on the volume of comments do not allow writing in more detail, but I give you enough tips on key topics.
Or here: A man quoted the beginning of an article from the Western press:

Quote: luiswoo

... for 9x19 there were stop bullets comparable to .40S & W.

But at the end of the same article, we learn that .40SW nevertheless remains the main and very popular caliber in the arsenal of the American police and other law enforcement agencies, as well as in the civilian market. And he’s not going anywhere.
As always, journalists pass off yet another "fried duck" as a sensation, themselves inflating the problem from scratch. And you feed on these ducks. Learn to think with your own head and analyze, and not spread rumors and gossip. Good luck

Quote: Mayor_Vikhr

Now compare such a bullet with a fraction of a shot in a short barrel of a pistol / revolver? If you shoot at close range, then the fraction may well be nothing. And then 10 meters I'm not sure that the pellets will have sufficient accuracy. Yes, and energy, and hence slaughter, they will lose much earlier than a large solid and heavy bullet. With a rainproof bullet, a similar picture.

You confuse this bullet with a container. Here the fraction is released only when it enters the carcass or obstacle.

[luiswoo]

Quote: Mayor_Vikhr

Continue to reason logically: new 9-mm bullets have appeared, respectively, similar .40 and .45 calibers have appeared, the effectiveness of which is even higher. Right?

Rather logical - comparable are not equal. About bоlower returns and less ammunition, we tactfully do not remember, right? If you do not get into vital organs, then the problems will be independent of caliber.

[4thParasinok]

in the USA it is allowed to have a bunch of different trunks to one frame. It turns out designers for almost all occasions. And to buy a trunk and a store is cheaper than a gun, the weight is true ...

[beresa]

Here is an example of a modular pistol developed by Stechkin, the OTs-27 Berdysh
The design of the OTs-27 pistol combines simplicity with original and very practical solutions. Automation works on the principle of using recoil with a free shutter. The shutter-casing was held in its extreme forward position by a return spring located on the barrel, and its own weight, locking the barrel channel. The barrel itself is quick-detachable, which allows you to adapt the weapon for firing with cartridges of another caliber in the field, and its replacement takes only about 40 seconds. The gun can shoot cartridges 7,62 × 25, 9 × 18 and 9 × 18 PMM, 9 × 19.

called "assault pistols"

yes .. for the assault it is better to take small-sized software.
"Externally, the MPA30DMG looks like some submachine guns"Does this barrel remind me of Ingrem Mac 10 to me alone?

So this shooter is a restyled ingram, they added caliber by removing 9X17, made a plastic handle and moved the platoon handle because of the picatinny rail.

Pathos nedoIngram. But there are buyers on this garbage.

For military and police needs is not suitable. In all respects, it falls under the category of civil-sports model, for amateurs: the lack of continuous fire, large dimensions, conversion kits.

no less pathos and empty post.

And Ryabov Cyril, as usual in his repertoire - an article at the level of a brochure - will have to be supplemented.
This desk - MastePiece Arms is interesting in that, on the basis of engram receivers, dozens of different models are riveted for different cartridges with different barrel lengths and, most importantly, with different work patterns - this wunderwolf has a trigger trigger and shoots from a closed (in the forward position) bolt, in contrast to the M10 / 11 and their n / a versions in the form of "assault pistols" firing from the rear sear.

[Nova]

I'm sorry, but what is your post with the obvious data more informative and "not pretentious" my opinion about this product? Or is it the norm, in discussion weapons go from first phrase to personality? Take care of your upbringing, my dear, before criticizing other people in the first lines of your message, instead of discussing weapons. And better - take and write your article about this gun, with your analysis and calculations, since Kirill Ryabov, in your opinion, simply wrote an advertising post.

[padonok.71]

I have no doubt that this misunderstanding will find its buyer. In America, there are a lot of people who are advanced on the topic of militarism, which are written in boiling water from all kinds of military pieces. Then there are the tanned inhabitants of the black ghettos, the Mexicans, in whom the size of the gun is of prime importance, regardless of the combat potential. Weapons of the first category (full auto) are practically impossible to buy and are being hungry.
Regarding specifically this miracle. I was pleased with the fuse box - what did the designer expect it to turn on / off? The transfer of the shutter platoon petal made it almost impossible to carry the gun in the cabaret. Apparently because of this they stuck such a noble swivel to the place where the butt should be. The store’s latch button just sticks out delightfully, I think inadvertently reset the store - a couple of trifles.
Commerce - in a word.

Quote: padonok.71

Now try to look at both phrases from the other side at once. After the adoption of the law on "assault weapons", all manufacturers rushed to rivet small-sized P / P versions. Ingremovskiy "assault pistol" was the most "friendly" to converting, dozens of firms offered USM parts (fortunately, the production and sale of such parts is not punishable there) by simply replacing which it turned into a full-fledged M10 / 11, then on a wave of criminal alterations by comrades from the ghetto / and a cobra with a modified receiver appeared in a full car, which no longer allowed simply rearranging the parts - and nevertheless, a cloud of instructions on how to remake its trunk appeared in the same place, then parts appeared specifically for it.
So in the ghetto, such shooters are not loved for brutality, but for the low cost and the possibility of easy alteration, which concerns this instance - I think that he does not face the popularity of cobra in the ghetto - the price is decent, but the trigger and shutter are different.

[padonok.71]

I agree and disagree. If the detectives take you for bells with such a "alteration" - write wasted, you will get 5-7 years of the sanatorium, maybe for life, they will. Therefore, if you really need a machine gun, then buy more budget tapestries, Filipino, Mexican, Chinese AK. Filipino Ingram can be bought for 200 dalars and it will stand up to a couple of stores. But such things as presented here are bought for legal wearing, well, as legal, you understand. And the maximum you can get for it is six months or a year. But it looks scary and it is not known whether it is upgraded or not. Ponty is shorter than black but oily. As we have Caucasians with pneumatics and injuries, you need to look scary, but so that they would not be imprisoned. Papuans that take.

Quote: tchoni

I don’t quite understand what are the advantages of modularity for the user?

And there are no advantages, there is only the manufacturer's benefit. For example. There is a single average American shooter. He goes to the store for, say, 911m and has 800 dalars with him. He comes and says to the seller: "Give me a 911". And he replies to him: "Here, choose, there is from 150 dollars. For some production, up to 300 dollars. For a native Koltovsky with pearl cheeks and Hemingway's autograph." Shooter to him - But how much is the normal inexpensive? The seller is a licensed Starrovsky for 000, okay? Shooter - okay, take it! Seller - Wait. Take it and you will have only one. 600 cal., And the cartridge is expensive, but you can see that you are a cool shooter and you burn thousands of cartridges at the shooting range, and the repair barrel 45 barracks is expensive. Shooter - and what to do? The seller - look cho is, the latest squeak / drysk of fashion, modular miracle assault pistol MPA200DMG, for only 30 see which one! Shooter - he is some kind of dumb. The seller is dumb! You cho! Real military Ingrem, all mariners go with such! Shooter - damn it, I don't know. The seller - you don’t know that! It's modular! Look, you want such a barrel, you want this one, any caliber from 679,99 to 38! Know only modules change. Shooter - is it expensive? The seller is a mere penny, 40 rubles per barrel, and 100 for a Colt! How much money do you have? Shooter - 200. Seller - take a pistol and a long barrel and I'll give you a discount and a tactical belt as a gift, like a mariner! And next week you will get your salary and let's go for a new module! Shooter - Wow! Kull! I take it! I take it! I take it!
The whole thing is done. The next day at the shooting range, having infected another couple of the same shooters - a military man! like the mariners! will carry money for another module. And there is also a LCC, a collimator, a flashlight, five kinds of belts, etc. And in total, it will carry 3-4 thousand, instead of 800 barracks.
Here is such modularity.

[DimYang]

The purpose of this gun is not clear. Who will the end user be?

[Vladimir 23rus]

Article is a plus, and a pistol is a minus. Long thought where I saw him? Remembered (blaster) Star Wars !!! ... Well, why does a PISTOL need a Picatinini rail? Hang up a sniper scope? There is nothing more for show-off in front of neighbors (black mattress covers shoot white cops ).

PS Maybe for one thing and explain to me, oh great gurus, why this is interesting in the works of Marshall and C know, and what is typical based solely on real statistics, without any pseudoscientific theories, the coefficient of EIR of a bullet .44 magnum turned out to be lower than the coefficient of a bullet .357 magnum respectively 96% and 90%, although 44 seems to be more like a caliber and the energy is also higher?
