The M2 Field is the workhorse of the Benelli semi-auto line. Light, nimble, but ruggedly built, the Benelli M2 is 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 in. target loads to the heaviest 3 in. magnums. Benelli engineers have also adapted the ComforTech 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 you back on target up to 69% faster than any other comparable semi-automatic shotgun. The M2 is not only faster, but with the new ComforTech system, it may be the most comfortable shotgun you ever will shoot. The M2 is a workhorse with the speed of a thoroughbred.
