Blowback-operated semi-automatic double-action pistol chambered for 7.65mm cartridge. Patterned after Walther Model PP, with a few differences. Safety catch is located on frame instead of slide; trigger guard is not hinged as on Walther. Dismantled by means of a catch on side of the frame. Intended to be a military pistol designed by Kratochvil brothers, it proved to be underpowered and was adopted by the police. Few were released on the commercial market.
