Description

This TNW Inc. Suomi M31 “Tanker” semi-automatic pistol is a faithful and functional homage to Finland’s iconic KP-31 submachine gun, historically fielded in WWII. Converted to semi-auto to meet federal regulations, this compact variant features a 12.5" barrel with a ventilated shroud and short pistol configuration designed for maneuverability—especially useful in close quarters like those in armored vehicles.

Chambered in 9mm Parabellum and equipped with a detachable 71-round drum magazine, the M31 Tanker brings classic military styling to the range. It sports a parkerized finish with handsome wooden grips, a tangent rear sight graduated to 500 meters, and a rugged partridge front sight. Whether you're a collector of historical arms or a recreational shooter seeking unique range gear, this Suomi M31 delivers heritage, capacity, and conversation-starting aesthetics.
