You guys are all right!
Beretta owns Benelli.
Beretta made recoil operated guns...like my Pintail.
Benelli makes a gas gun.
Beretta vs. Benelli is a win-win.
The question is which system is better?
Recoil/inertia driven guns have more felt recoil for the most part...but they have fewer parts to break, clean and jam up. Recoil guns were known as more reliable.
Gas guns were more picky about ammo, harder to clean and they broke more often. They had less felt recoil.
Today things have changed. Many manufactures have the gas gun perfected for reliability and ruggedness. The Beretta is a fine gas gun!
On the other hand, Benelli has reduced the felt recoil on their guns with stock inserts and so forth. Benelli is also a fine gun.
Gas guns are more popular across the board, but a inertia driven gun is also a fine choice. Shoot em all, and pick the one you like best!
