Overview

The Beretta M1918 was an Italian submachine gun designed by Tullio Marengoni and adopted by the Royal Italian Army in the final year of World War I. Developed from the twin-barrelled Villar Perosa, it mated a single Villar Perosa action to a wooden Carcano-style rifle stock and a top-mounted box magazine, firing the 9mm Glisenti cartridge. It is widely regarded as one of the first true submachine guns, alongside the German MP18.

Notes

The original M1918 used a single trigger for semi-automatic fire; the M1918 'due grilletti' (dual-trigger) variant added a second trigger for full-automatic fire. The M1918/30 was a 1930 redesign that moved to a bottom-mounted magazine and was offered in 9x19mm Parabellum.

Background

By splitting the twin-barrelled Villar Perosa volley gun in half and bolting one half to a rifle stock, Beretta turned a fixed aircraft and trench weapon into a shoulder-fired arm, producing what many historians count among the very first submachine guns.
