The Benelli M1 is a semi-automatic shotgun manufactured by Benelli Armi, and the first model of the Benelli Super 90 line of semi-automatic shotguns. Introduced in 1986, it is available in several versions for civilian, law enforcement and military use.
The M1 features the proprietary Benelli recoil system. The standard model features an aluminumalloy receiver and tubular magazine, and it is available with standard or pistol grip stocks. The M1 Super 90 can be fitted with traditional iron sights, or ghost ring sights. Mounts are available for laser pointers and tactical flashlights.
Due to the inertia recoil system, the M1 requires heavier loads to cycle properly. By having the action be inertia driven instead of the traditional gas cycling operation, it can fire and reliably cycle lighter loads.
