Anderson,
I have the same gun which had the same problem except my is in 20 ga. My problem was caused by the area around the firing pin being so gummed up that the firing pin spring would not retract the firing pin back into the action when the gun was fired. Thus when the action was opened the bottom of the chamber/ extractor hit the extended firing pin(s) bending the firing pins. I found one bent and one broke. I would advise you to examine both.
Bad News: This gun was built/imported only a couple of years and I found no supply of parts.
Good News: I had Bill Van Fossan of Dandridge Tenn. make four of the firing pins for me. The price of 4 pins was $40.00. His web site is

I have a sketch of my pin with dimensions that I supplied to Bill to make my pins. My address is klworkman AT suddenlink.net Use the normal @ sign. Email me and I will attach the sketch for you to compare. I removed/replaced my own pins but I am sure Bill could do that also if you want to send the gun off to him. I did this last Friday and have nor fired the gun yet but I expect no problems,
