Following the Second World War, brothers Josef and František Koucký became the most important engineers of the CZUB.
They participated to some extent on designing all the company's post-war weapons.
High-capacity magazines may use either 20 of the 9mm rounds or 17 of the .40 rounds.
As of 2013, the model is used by the CZUB's factory shooters in the IPSC Standard division, with a custom-made version CZ 75 Tactical Sports Open being also available. The model is a development of the CZ 75 TS Open, available in 9×19mm Parabellum and 9×21mm with magazine capacity of 20 or 26 rounds.
The CZ 75 is a short recoil operated, locked breech pistol.
It uses the Browning linkless cam locking system similar to that used in the Browning Hi-Power pistol, where the barrel and slide are locked together on firing, using locking lugs milled into the barrel mating with recesses in the roof of the slide.
Consequently, a large number of other manufacturers began offering pistols based on CZ 75 design (see Clones, copies, and variants by other manufacturers).These had a different frame from standard versions allowing for more modifications.
