In its article, the publication distributed the space as follows:
In the first place is the Belgian submachine gun FN-P90, developed by FN Herstal. PP is built according to the bullpup scheme, the store is located behind the trigger. This allowed weapon more compact, retaining the trunk length of 256,5 mm with a total length of PP in 500 mm. Mounted on top of the receiver, the magazine holds 50 ammo. This solves the problem of a bulging store that may interfere with carrying. The FN-P90 rate of fire is 900 shots per minute, caliber - 5,7x28 mm.
In second place is the Mk 18 Mod 0 carbine (M4 CQBR). The author of the article, Kyle Mizokami, notes that although the Mk 18 Mod 0 carbine is not a submachine gun and uses 5,56x45 mm ammunition like the full-size M4 carbine, the 262 mm barrel makes it a very compact weapon. It was developed in the USA as a replacement for the Heckler & Koch MP5 for SEAL units. The first versions of the Mk 18 Mod 0 were equipped with a carrying handle, but later it was replaced with a Picatinny rail for attaching scopes and other equipment. The result, the author writes, is a powerful and highly effective weapon that is convenient to use in urban environments or on board a ship.
In third place is the Heckler & Koch MP7. Externally, the German MP7 submachine gun looks like a huge pistol, but inside it is hidden a modern automation system. A new cartridge has also been specially developed for the MP7. MP7 is a fully automatic submachine gun. As in the case of the Israeli Uzi, the magazine is inside the PP grip. This made it possible to reduce the length of the PP to 638 mm with the butt unfolded and 415 mm with the stock folded. Automation, built according to the scheme with a gas engine with a short stroke of the gas piston, made it possible to shorten the PP as much as possible. The cartridge 7 × 4,6 mm specially designed for the MP30 is designed for aimed fire at a distance of up to 200 meters and the most effective destruction of targets in body armor. The possibility of using magazines for 20, 30 or 40 rounds is provided. Currently, the MP7 is in service with a number of special forces.
In fourth place, the publication placed Heckler & Koch MP5. The German MP5 submachine gun, long considered an exemplary PP, is still in service with the police and the army in many countries around the world. This submachine gun is a miniature version of the G-3 rifle chambered for 9 × 19 mm Parabellum. As a rule, the MP5 is equipped with a 30-round magazine. The length of the PP with the butt unfolded is, depending on the modification, from 680 to 700 mm. There are various PP options. For example, the MP5SD with an integrated silent flameless firing device or the MP5K with a shortened barrel and forend and an additional grip. The MP5 gained worldwide fame in 1980, when British special services fighters used this PP to free hostages from the Iranian embassy in London. Soon after, it became the favorite weapon of special forces around the world.
And in the fifth, honorable place - PP-19-01 "Vityaz" of Russian production. For many years, the Soviet and Russian army relied on the AKS-74 — a shortened version of the AK-74. In 2000, Russia presented a replacement for the legendary machine gun - PP-19-01 Vityaz. Like the AKC-74U and the German MP5, the Vityaz is a smaller version of the machine chambered for the 9 × 19 mm Parabellum cartridge. His length with butt spread out - just 705 millimeters. Empty PP weight - 2,9 kg. The rate of "Vityaz" is 800 shots per minute, sighting range - 200 meters. The manufacturer sets on the "Knight" Picatinny rail, which allows him to install various sights.
