The Benelli M3 is one of the very few shotguns that utilize both a pump and a semi-automatic option. With the twist of a ring, the Benelli M3 can be swapped from semi-auto to pump action. While other guns have done the same, notably the SPAS 12, the M3 has been more successful.
The M3’s hybrid design allows a shotgun shooter to run any load they choose. They can use full-powered loads in a semi-automatic action to get tons of lead on target with reduced recoil, or swap to pump action to run less-lethal loads or low recoil loads. The design allows the gun to eat anything.
As a Benelli you know it’s a premium shotgun. The semi-auto action is Benelli’s famed inertia recoil system. This is a reliable system that Benelli has used in most of their semi-auto shotguns. The Benelli M3 was never as popular as the M2 or M4 variants but is a unique and interesting weapon.
If you want a shotgun you can shoot anything through the M3 will get the job done.
