The CZ Model 23/25 (properly, Sa 23/25 or Sa vz. 48b / samopal vz. 48b – samopal vzor 48 výsadkový, "submachine gun model year 1948 para") was a series of Czechoslovak designed submachine guns introduced in 1948. There were four generally very similar submachine guns in this series: the Sa 23, Sa 24, Sa 25, and Sa 26.

The Sa 23 (Czech: Samopal 23) series of submachine guns was first conceived just after World War II, when Czech arms designer Vaclav Holek developed a submachine gun patterned after the various conventional blowback designs of the time (the MP 40, Sten, etc.), but with some innovative updates.

2018年9月26日 · The Sa vz. 23 quickly established itself as the standard-issue SMG for the Czech Army during 1951-1952. The Sa vz. 24 (vz. 48a./52) followed in retaining the wooden stock but was chambered for the 7.62x25mm Tokarev cartridge instead.

The Sa vz. 23 (Samopal vzor 23) was a Czech submachine gun that was produced by Česká Zbrojovka. Work on the vz. 23 began in 1947 as part of a large-scale project at the CZ factory to design a new submachine gun to meet the requirements of the Czech Army.

The Sa 23 series were submachine guns with a telescoping bolt, in which the forward part of the moving bolt extends forwards past the back end of the barrel, wrapping around that barrel. This feature reduces the required length of the submachine gun significantly and allows for better balance and handling.

All Sa 23 series submachine guns are blowback operated, select-fire weapons which fire from open bolt. The trigger works as a fire selector – short trigger pull produces single shots, while long pull produces burst fire.
