Also known as: vz. 25, Sa 25, CZ Sa 25, CZ 247
Overview
The Sa vz. 25 is a Czechoslovak 9x19mm Parabellum submachine gun adopted in 1951, designed by Jaroslav Holecek at Ceska Zbrojovka Uhersky Brod. It is the folding-stock version of the fixed-stock Sa vz. 23, replacing the wooden stock with a side-folding metal strut that shortens the weapon for airborne and vehicle crews. Like the rest of the family it uses a telescoping wrap-around bolt that overhangs the barrel, feeds from a magazine housed in the pistol grip, and employs a progressive trigger that fires semi-automatic with a light pull and full-automatic with a deeper pull.

Notes
Fires from an open bolt using 24- or 40-round magazines; other than its folding metal stock it is mechanically identical to the Sa vz. 23. The 7.62x25mm Tokarev counterparts are the fixed-stock Sa vz. 24 and folding-stock Sa vz. 26.
Background
Its telescoping wrap-around bolt, which wraps forward over the barrel to keep the gun compact, predated and helped inspire the same trick later used on the Israeli Uzi.
