History
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 II. Most of the guns produced were supplied to the Waffen-SS. It continued to be produced in small numbers in the postwar period; 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 Škorpion vz. 61 and Sa vz. 23.
Design
The ZK-383 was originally designed to be a squad automatic weapon much like the British Bren and Soviet DP28, despite it shooting a pistol round and not a full sized rifle cartridge. It became an individual submachine gun which resembles the German MP 18. For a submachine gun, the ZK-383 was a heavy and robustly made weapon. Military versions possessed detachable barrels, an integrated bipod, and rifle type sights, components considered unusual in submachineguns of the era. The police variant, designated the ZK-383-P, lacked these features, as did the postwar ZK-383-H.
Features
The ZK-383 was fitted with a quickly detachable barrel. The lock/release mechanism was located beneath the front sight. It fires from an open bolt and by removing 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 British Sten. The manual safety was located in front of the trigger on the left side of the weapon. The ZK-383 had 2 firing modes, single and full auto. Selection was made via the use of a short or long trigger pull. The stock was made from wood and had a folding bipod. The guns featured a front peep sight and a rear adjustable leaf iron sight.
