Another lesser known copy was the DUX 53 (Latin for leader) submachine gun manufactured in Spain. The DUX 53 was chambered for the 9mm Parabellum cartridge. The DUX 53 was an almost identical copy of the Finnish M/44, and used the same box and drum magazines. In 1954, the weapon was adopted by the West German Border Guards- the Bundesgrenzschutz BGS. The DUX 53 was followed by the DUX 59 model that was developed by Anschütz in Germany. The DUX 59 had a few changes and upgrades, most of which were copied from other designs. The recoil spring was changed to an enclosed telescoping configuration like that used in the German World War II MP40. The trigger frame of the DUX 59 was reinforced on the sides of the magazine well, preventing the use of the drum or duplex magazine. A sliding safety lever was relocated above the pistol grip on the left side, and the folding metal buttstock was reinforced. A new curved magazine was developed for improved feeding. The DUX 59 was under development for many years, but basically it was a World War II design. The weapon was evaluated, but not adopted by the German military.
