Suomi submachine gun (Finland)Suomi M/26 submachine gun, caliber 7,65x22 Parabellum
Caliber:
9x19mm Luger/Para The Suomi ("Finland") submachine gun was developed by Finnish arms designer Aimo Lachti in 1920-1930 period. First prototype was built by 1922, and by 1926 Lahti produced a working weapon, chambered for then-standard Finnish army's 7,65x22 Luger / Parabellum ammunition. Definitive version of the Suomi submachine gun was adopted by Finnish Army in 1931 as Suomi-KP Model 1931, or simply KP-31 (KP stands for Konepistooli - Automatic Pistol in Finnish language). Suomi submachine gun was manufactured by Finnish company Tikkakoski Oy, and licensed to Denmark (Madsen), Sweden (Husqwarna) and Switzerland (Hispano Suiza). Used mostly by Finnish and Sweden armies, it was also widely exported into Baltic countries, some European and South American countries. Suomi was used with great success during Winter War of 1940 against Soviet Union, when, wisely used, this SMG showed to the world the importance of the submachine guns to the modern warfare. Manufacture of the Suomi was ceased in Finland in 1944, but it was used well until the 1990s, when finally rendered obsolete and replaced in Army by assault rifles. Suomi submachine gun is a blowback operated,
selective fire weapon. It fires from the open bolt, and used so
called "differential locking" or "advanced primer ignition" principle,
when fixed firing pin ignites the primer BEFORE the bolt stops on its
way forward into the battery, so the bolt momentum of inertia is used
to lock the chamber during the initial phase of shot, when pressure in
the chamber is high. The bolt and receiver were machined from high
quality steel and bolt was fitted to the receiver almost airtight. The
rear cover of the receiver was screwed on to it also almost
hermetically. This was necessary to achieve a fire rate reduction by
using a simple vacuum valve in the receiver cover - when bolt moved
back, the valve let the air out easily from the space behind the bolt.
When bolt started to move forward, the valve closed itself, so
difference of air pressures behind the bolt and in atmosphere slowed
the bolt on its way forward into the battery. In general, the Suomi KP-31 was a highly effective, reliable and accurate gun, but too expensive to manufacture. | |
