BXP Submachine Gun

The Bergmann MP-18 is the world's first practical submachine gun, designed by Theodor Bergmann in 1918. It was developed for the German Army during World War I to provide infantry with a high volume of close-range firepower. The MP-18 fires the 9x19mm Parabellum cartridge from a 32-round drum magazine. It uses a simple blowback action with an open bolt. The MP-18 established the basic concept of the submachine gun that would dominate close-quarters battle for decades.

The Sa vz. 25 is a variant of the Czechoslovak vz. 23 submachine gun featuring a folding metal stock instead of the fixed wooden stock on the vz. 23. It was designed for use by paratroopers, vehicle crews, and special forces who needed a more compact weapon. The vz. 25 shares the same telescoping bolt action and receiver as the vz. 23. Its folding stock folds to the side, reducing overall length for storage and transport. The weapon is chambered in 9x19mm Parabellum and feeds from a magazine inserted in the pistol grip.

The Beretta M12S is an improved version of the Beretta PM12 submachine gun, a blowback-operated weapon in 9x19mm. It features a telescoping bolt design that allows a compact overall length while maintaining a longer barrel. The M12S relocated the safety from the rear of the receiver to the trigger guard for easier access. It has a 200 mm barrel and a cyclic rate of 550 rounds per minute. The M12S was adopted by Italian military and police forces as well as numerous other countries.
