I have three guns, a gas-operated, a long recoil operated and a Montefeltro Super90. The best of all is the inertia operated shotgun. This is why I love Benelli shotguns, just because of there system... SIMPLICITY! The more an object is simple the better it is, in anyway! I have 7 friends who go hunting on land & out at sea, and they have M1's, SBE 1 & 2's, 121's & 123's . You really wouldn't recognize either gun unless said these are Benelli's, all rust & dirt! And they just keep on firing. Why? because they are made simple. 3 of these friends had gas-operated guns and they switched to Benelli's just because they could'nt stand up to all that abuse!
