The production of the ZK-383 continued at Brno arms factory even during the German occupation during World War Two. Most of the guns produced were handed to the Waffen-SS. It continued to be produced in small numbers to European countries; Bulgaria continued importing it right up until 1970, 4 years after production finished. The ZK-383 was slowly phased out by smaller and lighter submachine guns such as the Skorpion vz. 61 and Sa vz. 23.
