The Beretta AL391 is a semi-automatic shotgun. It is manufactured, marketed, and distributed by Fabbrica d'Armi Pietro Beretta, in Gardone Val Trompia, Italy. The AL391 is most often used for hunting birds, and for clay target games such as trap and skeet. There are several different models, each with multiple variations. The AL391 is chambered in either 12 gauge or 20 gauge. The Beretta AL391 is mechanically similar to its predecessor, the AL390, but has a slimmer fore-end and a different shaped stock. It has an aluminum receiver, which reduces the weight of the gun. The magazine holds three rounds, providing a total capacity of four rounds, which can be reduced using a magazine plug. The gun has a magazine cut-off, which can be engaged to remove or replace a chambered shell without feeding a new round from the magazine.
