About
What it is, and why it matters
The Beretta Model 38 (Moschetto Automatico Beretta Modello 1938, MAB 38) is an Italian submachine gun designed by Tullio Marengoni and adopted by the Royal Italian Army in 1938. Chambered in 9x19mm Parabellum and fed from a 40-round magazine, it featured a robust tubular steel receiver, a perforated barrel jacket, a full wooden stock, and a distinctive dual-trigger system in which the front trigger fired semi-automatic and the rear trigger fired fully automatic. Widely regarded as one of the best submachine guns of the Second World War for its accuracy, reliability, and build quality.
Captured MAB 38s were highly prized by both Allied and German troops, who considered the Beretta one of the finest submachine guns of the war owing to its accuracy and craftsmanship.
The dual-trigger arrangement allowed instant selection between semi-automatic and full-automatic fire without a separate selector switch. Successive wartime variants (38/42, 38/43, 38/44) progressively simplified manufacture by removing the barrel jacket and shortening the barrel.
