CZ (CHEE-ZET) stands for Česká zbrojovka which means Czech Armory. Most CZ-marked firearms are connected with Česká zbrojovka Uherský Brod (ČZUB) – a Czech firearms manufacturer since 1936. CZ is a registered trade mark.
In the bygone era there were however other factories associated with the name Česká zbrojovka ("Czech Arms Factory" in Czech), often rendered simply as "ČZ" in general. Below you can find list of different producers of weapons in Czech republic of all the times.
The factories include:
Firearms made in many different factories in Czechoslovakia and later the Czech Republic have been sold under the name ČZ, Brno or Vz.
ČZ (or CZ) is an abbreviation of Česká zbrojovka, while vz. (or Vz., vz, Vz) is an abbreviation of vzor ("model"). In most cases, only weapons adopted by the Czechoslovak or Czech military have sign "vz." in the name, although there are some exceptions from this rule. Sa (or Sa.) is an abbreviation of samopal ("submachine gun"). The Czech army used the term "samopal" for Sa vz. 58 though it is an assault rifle, so this may be as an analogy to Russian term automat.
Note that military weapons were after World War II designed by several independent development centers (e.g., ZVS-VVÚ Brno, VTÚVM Slavičín etc.) and then assigned to a production factory.
Czech Weapons (ČZW) was a subsidiary group of Česká zbrojovka who develops and evaluates firearms.
