ZK-466: CZ Makes a Folding Submachine Gun

The ZK-466 was one of the post-war submachine guns developed in Czechoslovakia as part of the competition for a new Czech military SMG. Developed by Josef Koucky (who was also designer of the ZK-383 before the war), it is a 9x19mm open bolt simple blowback system with a collapsing stock and folding magazine well using ZK-383 magazines. It was designed in 1946, and it was Koucky’s sixth design project for the year (hence 46 6 in the designation).

The ZK-466 was part of the large trial in 1947, and a different system won the military contract. After that, Brno attempted to sell the gun on the export market instead. It was marketed as a pilot’s survival weapon on account of its compact nature, but was unable to find any interested buyers. A total of 22 were made, with the largest sale being five examples sold to WF Bern in Switzerland in 1949. A second slightly improved model was also made, but this didn’t attract any additional interest and the project was dropped by the end of 1950.

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