The Škorpion vz. 61 is a Czechoslovak compact submachine gun designed in the early 1960s, initially chambered in .32 ACP (7.65×17mmSR Browning), while later variants are available in 9mm Makarov, 9mm Parabellum and .380 ACP. It features a wire top-folding stock and uses a standard 10/20-round magazine.
The Škorpion was originally intended (an served mostly) as a compact sidearm for tank crews and other vehicle crews. Even today, it is in active service in the Czech military (now issued mainly to guards) and in elite police squads.
