Instead of being built around one of these operating systems, the Benelli M3 Convertible incorporates both a semi-automatic and pump-action mechanism. This allows users to have total reliability in semi-automatic mode with all conventional shotshells. Shooting a low-recoil or beanbag load? Simply turn the selector ring on the gun, which locks the action bars to the moveable fore-end. The Benelli M3 Tactical semi-auto pump shotgun offers dual operation. You can choose either semi-auto or pump action, depending on the specific purpose. The M3 delivers fast cycling semi-auto fire with conventional loads or pump-action for low-energy, special purpose loads.
