The Benelli M2 Field is the workhorse of the semi-auto Benelli shotguns, with the speed of a thoroughbred. Light, nimble, but ruggedly built, the M2 12-gauge shotgun and the M2 20-gauge shotgun are built around the ultra-reliable Inertia Driven bolt mechanism. The Inertia Driven system allows the M2 to digest nearly any 12 gauge cartridge, from 2-3/4" target loads to the heaviest 3" magnums. Benelli M2 Field 12GA Satin Walnut Shotgun 11011
