The MP 41 is a submachine gun produced by Haenel Waffen und Fahrradfabrik during World War II. It was a hybrid design that combined the receiver and bolt assembly of the MP 40 with a wooden rifle stock and a selector switch for semi-automatic fire. The MP 41 was produced in limited numbers and primarily issued to Waffen-SS and police units. It is one of the few German submachine guns of the era to offer a semi-automatic firing mode.

The MP 38 is a submachine gun developed by the German company Erma Werke and adopted by the German military in 1938. It was one of the first submachine guns to feature a folding stock and extensive use of stamped metal components. The MP 38 uses a simple blowback action and fires the 9x19mm Parabellum cartridge. It introduced modern manufacturing techniques that influenced subsequent submachine gun designs worldwide. The weapon is known for its compact size and high rate of fire.

The Beretta M38/42 is an Italian submachine gun produced during World War II as a simplified version of the earlier Beretta Model 38. It was designed to reduce production costs while maintaining the excellent reliability of the original design. The M38/42 features a simplified receiver made from stamped steel rather than machined components. It uses a unique two-trigger system: the front trigger for semi-automatic fire and the rear trigger for fully automatic fire. The weapon was highly regarded by Italian and German troops for its accuracy and reliability.
