The M1 was succeeded by the Benelli M2, Benelli M3, and Benelli M4 models.

The M1 features the proprietary Benelli recoil system. The standard model features an aluminum alloy 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.^[1]
