Originally designed by Beretta’s chief engineer Tullio Marengoni in 1935, the Moschetto Automatico Beretta (Beretta Automatic Musket) 38, or MAB 38, was developed from the Beretta Modello 18 and 18/30, derived from the Villar Perosa light machine gun of World War I. It is widely acknowledged as the most successful and effective Italian small arm of World War II and was produced in large numbers in several variants. Italy’s limited industrial base in World War II was no real barrier toward the development of advanced and effective small arms since most weapons of the time required large amounts of artisan and semi-artisan man-hours to be fine-tuned anyway. Italian specialized workers excelled at this, but the initial slow rate of production meant that the MAB 38 only became available in large numbers in 1943 when the fascist regime was toppled and Italy split between the Allied-aligned co-belligerent forces in the south and the German-aligned collaborators of the Italian Social Republic in the north.

MAB 38, in its first variants, was a fine weapon by any standard, crafted with high-quality materials, flawlessly finished, and with carefully machined parts. Models 38/42 and 38/44 were easier and faster to build, the finish was sacrificed for speed of production but the quality remained high. The mechanism was a traditional simple blowback recoil but with a novel floating firing pin, an automatic safety on open bolt (both later removed to save production costs), a recoil compensator on the muzzle, a bolt cocking handle with sliding dust cover and a striking trigger gear with no fire selector but with two triggers instead; the fore trigger was for semi-automatic fire and rear trigger for full-auto. The user could shift quickly between methods without switching levers or safety catches, which proved useful in combat. The full-auto trigger had a safety catch on the left side, which was eliminated from 1942 and the rear sight was adjustable up to 500 m (550 yd) in the MAB 38 and 38A, the 38/42 and 38/44 variants had fixed rear sights. The MAB 38 had a wooden stock, was about 800 mm (31 in) long and weighed about 5 kg (11 lb) when loaded, with an effective range of about 200 m (220 yd).
