The Samopal vzor 23, more commonly known as the Sa vz. 23 or the CZ Model 25, is a Czech submachine gun.

HistoryEdit

Designed in the 1940s and used up until 1968 when it was officially declared obsolete, the vz. 23 was used by many nations around the world, most notably third-world nations. After being declared obsolete, the surplus weapons were exported to other communist countries including North Vietnam. Interestingly, many 9×19 models were purchased by South Africa during apartheid. These were converted to semi-automatic fire only, for sale and use by white farmers as protection during the country's difficulties. The vz. 23 was based on the prototype CZ 447 submachine gun.

Design DetailsEdit

Design features of the series included the now familiar magazine in pistol grip and telescoping bolt which enable a much shorter weapon even with a longer barrel. The 7.62×25mm-chambered submachine gun was particularly effective due to the very high velocity of the projectile approaching the US M1 carbine, although with a lighter bullet. This gives the 7.62mm version much greater effective range than any 9mm submachine gun; in fact, with its near rifle like velocity, the cz. 24/26 can penetrate most bullet resistant vests now in use by police agencies. Only the much bulkier vests such as those worn by SWAT teams will reliably stop this round. The only difference between the Model 23/25 is that the Model 23 has a fixed buttstock, whereas the Model 25 has a folding stock. The same difference occurs in the 24 and 26 models which are fixed and folding respectively. Uziel Gal would later use some ideas and design features from the vz. 23 and implement them into his design, which would later become known as the Uzi.
