Dreyze Pistol Model 1907 of the Year (1907 Dreyse Pistol): device and disassembly procedure
In 1901, the company acquired Waffenfabrik von Dreyse (Waffenfabrik von Dreyse), which had previously manufactured needle-rifles, pistols and revolvers. After the appearance of unitary cartridges and the adoption of the Mauser rifle by the German army in 1872, the demand for needle weapon Dreyse began to decline sharply and the company almost went bankrupt.
The new owners acquired not only the plant, but also the rights to the patents and the Dreyse name. After that, RM&M began producing several types of firearms under the Dreyse trademark.
Dreyze Pistol Model 1907 of the Year Dreyze Pistol Model 1907 of the Year (1907 Dreyse Pistol) was patented on February 21, 1908 by Rheinische Metallwaren & Maschinenfabriken. The pistol was designed by Louis Schmeisser, although his name did not appear on the patent.
This patent describes the design of the bolt and front sleeve, fixing the return spring, without focusing on the hinge connection. Automatic pistol works by returning the free shutter. The box-shaped detachable gun magazine is designed to accommodate 7 ammunition Browning caliber 7.65mm Auto (.32ACP). The total length of the gun 160 mm, weight without cartridges 710 grams, barrel length 93 mm has four right-inclined rifling.
There is another RM & M patent, registered in Germany under the number 185411, dated January 4, 1906, which shows a similarly designed hinge joint between the pistol frame and the receiver. The drawings for the patent show a pistol very similar to the Bergmann Simplex. Probably this patent became the basis for the technical solution in the Draize 1907 pistol.
The success of the Browning pistol at the beginning of the 20 century pushed many designers to copy the design of this pistol. The Dreyse 1907 pistol was also designed under the strong influence of the Browning design of the 1900 model of the year. The tilt angle of the handle, the caliber of the ammunition used, the design of the store, the amount of ammunition, the principle of operation of the automation, the design of the magazine latch, the design and location of the fuse are very similar to the Browning 1900.
However, Louis Schmeisser introduced a lot in the design of the gun. The return spring from the Dreyse 1907 model is placed around the barrel, and not above it, like the Browning. The original design of the front sleeve makes it easier and without loosening the screws to do an incomplete disassembly of the weapon. The swivel top of the gun with the frame simplifies maintenance and cleaning of the weapon.
The fixed part of the receiver closes about three-quarters of the shutter. For this reason, the notches for the convenience of gripping the bolt by hand are located in front, not far from the muzzle. On the right side in the receiver there is an oval window for extracting the spent cartridges. The ejector, which is a flat narrow plate placed on the right side of the shutter.
A button with a vertical notch is mounted on the back end of the gun. When the button is moved to the right, the upper part of the pistol: the barrel with the receiver and bolt is separated from the back of the frame and rotates upward with respect to the frame. In a pistol standing on a platoon to move the button and open the receiver is impossible.
Articulation of the upper part of the gun contributes to the ease of cleaning, lubrication and maintenance of weapons. In addition, it facilitates disassembly of the pistol and removal of the bolt from the receiver. The reflector plate is installed on the left side of the receiver. The reflector is fixed in the receiver with a screw. The bolt contains a drummer, an ejector and a platoon indicator.
The Dreize pistol of the 1907 model of the year has a pointer of a cocked drummer in the form of a rod protruding from the back of the bolt.
The barrel is fixed in the receiver and pivotally connected to the frame of the gun. The screw that holds the reflector simultaneously fixes the barrel in the receiver. After unscrewing this screw, the barrel can be unscrewed from the receiver using a special tool. The recoil spring is held in place around the barrel with a sleeve located in front of the receiver. The protrusion "t" -shaped in the upper part of the sleeve is included in the recess of the lower part of the gate. When you move the bolt back, he pulls the sleeve, which compresses the return spring. In early pistols, the protrusion was located not on the sleeve, but on the gate.
The trigger pistol Dreyse gun model 1907 of the year (1907 Dreyse Pistol) fairly simple design. The trigger lever connects the trigger with the sear. The uncoupler, which has the shape of a crescent on most pistols, retracts the trigger lever when the shutter moves and therefore it cannot touch the sear until the shooter releases the trigger.
The trigger mechanism during the entire production periodically subjected to modernization. Basically the form was whispering. The early whispers just let the drummer go. In pistols of a later release, the drummer was a little backed away, additionally compressing the mainspring, and only then let them go with the platoon. This was done to ensure uninterrupted pistol shooting when contaminated, at low temperatures and when using ammunition with tougher primers. The manual safety device located in the rear part of the frame on the left reliably blocks the sear in the on state. Access to the details of the firing mechanism is possible after unscrewing the screws and removing the side plate of the frame located under the left cheek of the handle.
Sights gun represent the rear sight in the upper part of the receiver at its rear slice and front sight in the upper part of the shutter, almost at the muzzle. The front sight is recessed into a semicircular recess in the upper part of the shutter and the aiming line is limited by the edges of this recess.
Early pistols were marked on the left side of the receiver with the text DREYSE Rheinische Metallwaren- & Maschinenfabrik ABT. SOMMERDA ".
Later pistols were marked “DREYSE RHEINMETALL ABT. SOMMERDA. For pistols fired after 1914, the word "Dreyse" disappears from the labeling. The cheeks are black with a notch and a monogram in the form of the letters “RMF” in the upper part of the cheeks. Pistols issued for the police have certain marking features.
The serial number of the pistol is stamped on the right of the receiver above the trigger guard, as well as on the top of the bolt.
The serial number can also be seen on the top of the pistol frame in front of the store placement window. The highest serial number that is mentioned among researchers and collectors is #251211. The Dreyze pistol model 1907 of the year was produced in the period from 1907 to 1915 year. A total of probably less than a quarter of a million copies were released.

Move the locking tab on the back of the gun to the right.
Turn on the axis of the upper part of the gun with the barrel and bolt, separating the back of the receiver from the frame of the gun.
Using a screwdriver or another tool, push the return spring bushing to disengage it from the bolt. In this case, the sleeve must be held with the thumb of the left hand so that under the action of a rigid return spring the sleeve does not fly out and cause injury.

In 1912, it began to be used as a military pistol and became a replacement pistol for staff officers and rear troops. The pistol was purchased to arm parts of the army of Austria-Hungary and Czechoslovakia. There is evidence that the order of 2000 pistols was purchased for the Russian Army. Researchers mention several gun accidents, which are explained by loosening the latch at the back of the frame, thanks to which the drummer spontaneously falls from the whisper and a shot occurs.
