The PPS (Russian: ППС - "Пистолет-пулемёт Судаева" or "Pistolet-pulemyot Sudayeva", in English: "Sudayev's submachine-gun") is a family of Soviet submachine guns chambered in 7.62×25mm Tokarev, developed by Alexei Sudayev as a low-cost personal defense weapon for reconnaissance units, vehicle crews and support service personnel.
The PPS and its variants were used extensively by the Red Army during World War II and were later adopted by the armed forces of several countries of the former Warsaw Pact as well as its many African and Asian allies.
The Mars Automatic Pistol, also sometimes known as the Webley-Mars, was a semi-automatic pistol developed in 1900 by the Englishman Hugh Gabbet-Fairfax and distributed by the Mars Automatic Pistol Syndicate Ltd. of Birmingham. It was manufactured first by Webley & Scott and later by small gunmakers in Birmingham and London. Manufacture ceased in 1907.
The Mars Automatic Pistol is noted for being available in a variety of 8.5 mm, 9 mm and .45 calibres. These were all bottlenecked cartridges with a large charge of powder, making the .45 version the most powerful handgun in the world for a time. It used a unique long recoil rotating bolt action which ejected spent cartridges straight to the rear, and the feed mechanism is unusual in that it pulls cartridges backwards out of the magazine and then lifts them up into the breech face.
The Saiga-12 is a 12-gauge shotgun available in a wide range of configurations, patterned after the Kalashnikov series of rifles and named for the Saiga antelope. Like the Kalashnikov rifle variants, it is a rotating bolt, gas-operated gun that feeds from a box magazine. All Saiga-12 configurations are recognizable as Kalashnikov-pattern guns by the large lever-safety on the right side of the receiver, the optic mounting rail on the left side of the receiver and the large top-mounted dust cover held in place by the rear of the recoil spring assembly.
The Remington R51 is a semi-automatic pistol announced in January 2014. The R51 is a modernized version of the John Pedersen-designed Remington Model 51 pistol chambered in 9×19mm caliber. The company plans to offer the pistol in .40 S&W and other calibers in future. The layout of the Remington R51 is similar to the Walther PPK pistol in the use of a stationary barrel and recoil spring surrounding the barrel. However, the notable feature is the use of a locking breech block within the slide utilizing the "hesitation-locked" action originally developed by John Pedersen.
The RPD is a 7.62mm light machine gun developed in the Soviet Union by Vasily Degtyaryov for the intermediate 7.62×39mm M43 cartridge. It was created as a replacement for the DP machine gun chambered for the 7.62×54mmR round. It is a precursor of most squad automatic weapons. It was succeeded in Soviet service by the RPK.
The Heckler & Koch MP7 (Machine Pistol 7) is a German Personal Defence Weapon (PDW) designed and manufactured by Heckler & Koch (H&K) and chambered for the HK 4.6×30mm cartridge. It was designed with the new cartridge to meet NATO requirements published in 1989, as these requirements call for a personal defense weapon (PDW) class firearm, with a greater ability to penetrate body armor than current weapons limited to conventional pistol cartridges. The MP7 went into production in 2001. It is a direct rival to the FN P90, also developed in response to NATO's requirement.
The MP7 uses a short-stroke piston gas system as used on H&K's G36 and HK416 assault rifles, in place of a blowback system traditionally seen on sub-machine guns including those by H&K. The 4.6×30mm ammunition is exclusive to the gun and offers low recoil. This ammunition is unique among submachine guns in that the bullet is made almost entirely of a hardened steel penetrator instead of softer copper or lead.
The Heckler & Koch MP5 (from German: Maschinenpistole 5, meaning Submachine gun 5) is a 9mm submachine gun of German design, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (H&K) of Oberndorf am Neckar. There are over 100 variants of the MP5, including some semi-automatic versions.
The Bergmann–Bayard was a German designed semi-automatic pistol produced under license in Belgium.
Design aimed squarely at the military market, with a comparatively powerful 9×23mm Bergmann round. It aroused the interest of a number of armies and was the subject of several trials in competition with the Mauser C96, Mannlicher, Browning and Luger pistols.
The Owen Gun, which was known officially as the Owen Machine Carbine, was an Australian submachine gun designed by Evelyn (Evo) Owen in 1939. The Owen was the only entirely Australian-designed and main service submachine gun of World War II and was used by the Australian Army from 1943 until the mid-1960s.
