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.

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.
