Overview

The Madsen-Suomi is a Danish-licensed version of the Finnish Suomi KP/-31 submachine gun, manufactured by Dansk Industri Syndikat (Madsen) and adopted by the Royal Danish Army as the Maskinpistol m/41. Chambered in 9x19mm Parabellum, it is a blowback-operated, open-bolt weapon firing from a wooden stock and fitted with distinctive protective metal 'ears' flanking the front sight post. Roughly 1,400 were produced before Germany disarmed the Danish army in 1943.

Notes

Danish production ran only until the German disarmament of the Danish army in August 1943, keeping total numbers low. Fed most commonly from a 20-round box magazine, though it retained compatibility with the Suomi's larger box and drum magazines.

Background

When Germany disbanded the Danish army in August 1943, production of the Madsen-Suomi ceased with only about 1,400 built, and surviving guns were prized enough that some were smuggled away to arm the Danish resistance.
