ZKP-524: A Prototype Czech 7.62x25mm 1911 Copy

The Czechoslovak military knew when they adopted it that the vz.52 pistol was not very good, and they initiated a replacement program as the same time as its adoption. Two pistols were developed to be its replacement; the CZ 531 and the ZKP 524. The ZKP was designed by the brothers Josef and František Koucký, based heavily on the Colt 1911 and Tokarev TT33 pistols. It was chambered for the 7.62x25mm cartridge as required by the military, and held 8 rounds in a single-stack magazine. In trials against the CZ-531, it proved to be more accurate, but less reliable and more expensive. It suffered a cracked slide after 4,198 rounds fired, and an improved second example was made. However, the vz.52 proved good enough despite its shortcomings, and the program to replace it fizzled out after this testing.

Thanks to the Czech Military History Institute (VHU) for graciously giving me access to this unique prototype to film for you! If you have the opportunity, don’t miss seeing their museums in Prague:
