Historical profile
Developed by Jaroslav Holeček from 1946 and entering service in 1948, it was the first submachine gun to use a wrap-around bolt, a solution later adopted by the Uzi and MAC-10.
Produced in four main versions: vz. 23 (wood, 9mm), vz. 25 (folding metal, 9mm), vz. 24 (wood, 7.62 Tokarev) and vz. 26 (folding metal, 7.62 Tokarev).
Exported to Syria, Cuba and Africa; it deeply influenced subsequent submachine gun design thanks to the magazine housed in the pistol grip.
