The ZK-338 is a submachine gun and was developed by Koucký brothers who worked at the Zbrojovka Brno arms factory in Czechoslovakia. It was produced at a slow rate from 1938 and was exported as far as Latin American to Bolivia and Venezuela.[1]



The ZK-383 was exported to many smaller European countries following its production start date in 1938. 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.[1]


The ZK-383 was originally designed to be a squad automatic weapon much like the UK Bren and Russian DP28, despite it shooting a pistol round and not a rifle bullet. It became an individual submachine gun which resembles the German MP 18. The ZK-383 was a heavy and robustly made weapon which packed a serious punch despite its small round. A long range version was made which contained rifle type sights and an integral folding bipod.[1]


The ZK-383 was fitted with a quickly detachable barrel. This is very unlike many submachine guns. The lock/release mechanism was located beneath the front sight. It fires from an open bolt and by removing/adjusting the bolt weight, the shooter could vary the cyclic rate between 500 to 700 rpm. The magazine fed in from the left hand side like the Canadian and British Sten. The manual safety was in front of the trigger. The ZK-383 had 3 firing modes, single, full auto and safety.[1] The stock was made from wood and had a folding bipod in some variants. The guns featured a front peep sight and a rear tangent iron sight and were adjustable by the shooter to a maximum range of 600 metres.


  • ZK-383; Standard production variant
  • ZK-383P; This was the Police version which had no folding bipod
  • ZK-383H; The post-war production model which also had no bipod and instead of a left side magazine, had a forward facing underslung magazine. It still held 30 rounds
