The M2 Tactical is a no-nonsense 12-gauge shotgun that police and military the world over reach for when the going gets tough. The M2 Tactical, like all Benelli semiautomatic shotguns is Inertia Driven, which uses recoil energy to cycle the action. This eliminates all the problems associated with gas-operated systems, such as the necessity of frequent cleaning and the tendency gas-operated systems have for malfunctioning during adverse weather conditions. The M2 Tactical fires all 1º oz. or heavier 2¾" and 3" shot loads plus slugs. The M2 Tactical features a fully adjustable ghost-ring aperture rear sight and military-style fixed-blade front sight or adjustable rifle sights. In addition the M2 Tactical comes with either a matte black synthetic stock with tactical pistol grip, or with a ComforTech stock that reduces felt recoil by as much as 48%. The M2 Tactical is a shotgun you can bet your life on. Benelli M2 Tactical 12GA 3" 18.5" Black 5+1 Semi-Auto Shotgun w/ Pistol Grip 11052
