The 'Suomi KP/-31' (Suomi-konepistooli or "submachine gun Finland") was a submachine gun (SMG) of Finnish design that was in service during World War II. It was a descendant of the M-22 prototype and the KP/-26 production model, which was revealed to the public in 1925. The Suomi-konepistooli KP/-31 is often abbreviated to Suomi KP.
The Suomi KP/-31 is regarded by many as one of the most successful submachine guns of World War II and it was so successful that many of its features were later copied by the Soviets in their PPD-40 and PPSh-41 submachine guns.[2] The accuracy compared to the mass-produced PPSh-41 was superior, thanks in part to a noticeably longer barrel, with the same rate of fire and an equally large 71 round drum magazine. The major failing of the Suomi-KP was its high production costs.
