Beretta M1918: Italy's 9mm Semiauto 9mm Carbine from WWI
The Beretta M1918 is a rare Italian semi-automatic carbine from WWI, often mistaken for a submachine gun but firing only in semi-auto. It reuses parts from the 1915 Villar Perosa and operates from an open bolt with a delayed blowback system for safety. Chambered in 9mm Glisenti, it features a unique 25-round magazine and a trigger guard repurposed from a Vetterli rifle.
