Also known as: vz. 24, Sa 24
Overview
The Sa vz. 24 is a Czechoslovak 7.62x25mm Tokarev submachine gun adopted in 1951, designed by Jaroslav Holecek at Ceska Zbrojovka Uhersky Brod. It pioneered the telescoping wrap-around bolt that overhangs the barrel, allowing a long barrel in a compact receiver, and feeds from a magazine housed in the pistol grip. The vz. 24 has a fixed wooden stock and a progressive trigger that selects semi-automatic fire with a light pull and full-automatic with a deeper pull.
