The CZ Model 26 was perhaps the best known of 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 (September, 15 1923–October, 12 1997), chief engineer of the Česká zbrojovka Uherský Brod arms factory.

The Sa 23 series utilize a straightforward blowback action, with no locked breech, and fire from the open bolt position. They also use a progressive trigger for selecting between semi-automatic fire and fully automatic fire. Lightly pulling on the trigger will fire a single shot. Pulling the trigger farther to the rear in a continuous motion will fire fully automatically, until the trigger is released or the magazine is empty.
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. Handling was further improved by using a single vertical handgrip housing the magazine and trigger mechanism, roughly centered along the gun’s length. The gun’s receiver was machined from a single circular steel tube.
The design of the Sa 23 series submachine guns is most notable in the West for having inspired the open-bolt, blowback-operated, telescoping bolt design of the slightly later Uzi submachine gun.
