It is a pistol cartridge that was developed by John Browning and launched on the market in 1899. Americans usually refer to it as .32 ACP caliber. For a while it was also widespread in Czechoslovakia, e.g. in CZ 27, CZ 50, CZ 70, CZ 82 pistols. However, it has a rather low stopping effect, which is why this caliber is found rather exceptionally in modern pistols.
