Suomi KP/-31 (aka Suomi M/31), commonly known as Suomi sub-machine gun (Suomi konepistooli) in Finland, was a sub-machine gun based on the early Bergmann MP18 design. First designed in 1922, by Aimo J. Lahti, the gun was revealed to public in 1925. It is among one of the most succesful gun designs of World War II. The Soviets even later copied many of the designs for their PPSh-41 and PPD-40 sub-machine guns. The Suomi (which means Finland) KP/-31 was in service in the Finnish Armed Forces from 1931 to the 1960's, when it finally became obsolete as the Rk 62 replaced it. Altough, some special versions stayed in service up to the eighties.
