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.
