I have several Super 90's and shoot them A LOT - mostly in South America on doves. Only problem I've ever had is the two rivets on the ejector system working loose. My South American outfitters tell me that this is the most common Benelli problem that they experience, and also the most difficult to solve. The factory alloy replacements are simply too short to provice sufficient "grip" when installed. I've tried everything I can think of, including a tooled brass rivet, but can't come up with a good solution. Love the guns, but need to solve this problem. Anyone have any ideas?
