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 primary designer was Jaroslav Holeček (15 September, 1923–12 October 1997), chief engineer of the Česká zbrojovka Uherský Brod arms factory.
