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 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 engineers have also adapted the recoil system for the M2. This revolutionary system reduces felt recoil by up to 48% and cuts muzzle climb by 15%. When combined, this puts the shooter back on target up to 69% faster than with any other comparable semi-automatic shotgun. The M2 is not only faster, but with the new system, it may be the most comfortable shotgun you will ever shoot.
