Overview

The Beretta Model 38A (Moschetto Automatico Beretta 38, or MAB 38) is an Italian submachine gun designed by Tullio Marengoni and introduced in 1938. Chambered for the 9x19mm Parabellum cartridge and operating on a simple blowback system from an open bolt, it featured a finely machined steel receiver, a full-length wooden stock, a perforated barrel jacket, and a distinctive twin-trigger arrangement that selected semi-automatic fire on the front trigger and fully automatic fire on the rear. Adopted as the standard submachine gun of the Royal Italian Army as the MAB 38A in 1941, it earned a reputation as one of the most accurate, reliable, and best-built submachine guns of World War II.

Notes

The dual-trigger system gives selective fire without a fire-selector switch: the forward trigger fires single shots, the rear trigger fires fully automatic. Early production examples were fitted with a folding bayonet, later deleted to simplify manufacture. The simplified Model 38/42 with a shorter barrel and stamped components succeeded it from 1942.

Background

The MAB 38 series traced its lineage to the Villar Perosa twin-barrel aircraft gun of World War I via the Beretta Modello 18 and 18/30 carbines. Prized for its accuracy and build quality, it was widely sought after as a war trophy by Allied troops in the Italian and North African campaigns.
