Also known as: KP/-44, Peltiheikki

Overview

The KP m/44 (KP/-44) is a Finnish 9x19mm Parabellum submachine gun, a stamped-steel copy and modification of the Soviet PPS-43 produced by Oy Tikkakoski Ab late in the Continuation War. Operating on a simple open-bolt blowback action with a side-folding steel stock, it was cheap and fast to manufacture, and it accepted the same magazines and drums as the earlier Suomi KP/-31.

Notes

Adopted too late to see significant wartime service; production ended with the war. Chambered in 9x19mm rather than the Soviet 7.62x25mm of the PPS-43, allowing it to share Suomi KP/-31 magazines.

Background

Designed by German emigre engineer Willi Daugs, the KP m/44 was essentially a re-chambered PPS-43 so it could feed from the abundant 9mm Suomi magazines already in Finnish service.
