Mauser MP-57

The Mauser MP-57, officially the Maschinenpistole MP-57, was a West German submachine gun made by Mauser after the Second World War for the newly established Bundeswehr. It was designed by Louis Camillus between 1955 and 1957, and the article lists its variants as the Erma MP-56 and the Mauser MP-57. The weapon fired the 9x19mm Parabellum cartridge from a 32-round box magazine inserted into the pistol grip, and worked by blowback from an open bolt at a cyclic rate of about 800 rounds per minute. It weighed 2.80 kg and measured 610 mm in length, or 430 mm with the stock folded, with iron sights. The article gives a production date of 1957 and records only 25 examples built.
