All I can say is the SBE II is a P.O.S. I have had nothing but trouble from day one, called the factory and replaced the firing pin spring, recoil spring, and the feed tube spring and it still malfunctions. And all the hype about the comfortech system is B.S. in my opinion as well, I bought the Beretta Extrema II K/O Max4 and it is the ticket.
They day that did it for me was when I had 4 cotinential mallard drakes floating in a 20+ mph wind over the decoys and I jumped up to shoot and what happened nothing a malfunction again. I went to buy another one immediately after the hunt and picked 2 brand new SBE II's off the shelf and the both jammed when I racked the action.
No offense to the Benelli owners out there and I own one, so this is not a one sided opinion but mine can collect dust for all I care.
