SMG Czech 25 9 mm (VZ 25)The VZ 25 was designed by Vaclav Holek and was produced in 1949 along with the VZ 23, VZ 24 and VZ 26. They differ only in cartridge and butt stock. The VZ 25 is a standard 9 mm x 19 Parabellum and has a folding metal stock. The VZ 23 and the VZ 25 were in service with the Czech army in 1951 and 1952 and were then replaced by the 7.62 mm VZ 24 and VZ 26 which remained in service until 1962. One innovation was the placing of the magazine inside the pistol grip. Two sizes were made, one holding 24 rounds and the other holding 40 rounds.

It has compact size, but a relatively long barrel and allows one-hand fire. This is his history: History: This submachinegun has been developed during years 1948-1949 in Ceska Zbrojovka Strakonice (prototypes H/p, CZ 447, CZ 148). The main constructor was J. Holecek, other important participating constructors were J. Cermak, F. Myska, J. Kratochvil, V. Zibara. The final weapon design was derived from a considerably modified prototype CZ 447. On 10th august 1948, the submachinegun was accepted by army under name "9 mm samopal vz. 48a" (with a solid wooden stock) and "9 mm samopal vz. 48b" (with a folding stock). The mass production of submachinegun began in 1949 in CZ Uhersky Brod (in 01/01/1948, the factory was renamed as Zavody presneho strojirenstvi Uhersky Brod). In spring 1950, the machinegun was renamed: from Sa vz. 48a to Sa 23 (solid stock)from Sa vz. 48b to Sa 25 (folding stock)NOTE: Sa vz. 23 ( or 24, 25, 26) doesn't exist!!! Only Sa 23, 25, 24, 26. Number 23 (or 24, 25, 26) doesn't indicate year, so never put word "vzor" or "vz." (which means "model") to the name of this submachine gun. The number in the name of submachinegun indicates only some numerical specification. The mistake that I described is very spread (even in Czech rep./Slovakia). In year 1950, because of unification with Soviet Union army, the production of Sa 23/25 in cal. 9 mm Parabellum ended. The weapon has been modified for caliber 7.62x25 (Tokarev). On 11th june 1951, the modified weapons were accepted by czechoslovak army as Sa 24 (solid stock) and Sa 26 (folding stock). After that, the previous submachineguns 23 and 25 were discarded from army and offered to the public militia (or other armed sections), a lot of submachineguns was sold to the other countries. Sa 24/26 has not been in the service for a long time, because in 1958 it was replaced with a new assault rifle Sa vz. 58. Whole production of Sa 23/25 was about 136 000 pcs. Sa 23/25 were seen in the action in these countries: Tchad, Grenada, Guinea, Guinea-Bissau, Chile, South Africa rep., Cambodia, Capo Verde, Cuba, Libanon, Libya, Mosambic, Niger, Nikaragua, Peru, Somalia, Syria, Tansania etc - maybe these submachineguns are still in service in some countries (armed forces, guerrillas...). In South Africa rep. in years 1977-1980, there has been produced a simplified semiautomatic version of Sa 25 under name Sanna 77. And... of course, the famous submachinegun UZI was patterned after Sa 25 (magazine in the grip, breech enclosing the barrel etc.). Nowadays, these submachineguns are not used in any czech/slovak armed forces, sometimes is found when a crime is commited. Technically, al M23 SMGs were blowback operated, select fire firearms. The trigger works as a fire selector - short trigger pull produces sinle shot, while long pull produces burst fire. The wrap-around bolt has firing pin fixed into it near its rear end and encloses the breech part of the barrel with the most of its lenght when closed. Gun fires from the open bolt. Box magazines are inserted into the pistol handle (much like most semi-auto pistols, but first of all SMGs). All M23 family SMGs has built-in magazine loading device at the right side of the front guard, which is designed for loading box magazines from 8-rounds stripper clips. The charging handle is located at the left side of the gun. The sights are: hooded blade front sight and distance-ajustable drum rear ones. The 7.65 and 9mm models can be distinguished by the magazine insertion: 7.65mm models have magazines that slope forward whereas those of the 9mm models are vertical.
UZI had been developed on the basis of the Czech M23 and 25 submachine gun, utilising its overall design and many features, but with completely different receiver (rectangular instead of round in cross-section) and other changes.
