Benelli wants to sell me the entire cap and stud. I don’t need a new end cap just the stud. I will give them a try with the part #. I have owned the gun since 1996 and never had an issue with loading it until recently. I attempt to put the shells in the mag. and they jam, I take it out and try to put it in again and it goes in easy. Other times you need to loosen the barrel. I think the mag. spring may be going. I was wondering if anyone had experienced this problem. Thanks for your help.
