new to this forum ... I have a charles daly o/u that my dad owned for 20 years maybe. I am starting to try to shoot trap with it. The first time I took it out I noticed that the action would not open after shooting. Further inspection reavealed that the firing pin was staying stuck in the primer. I had to hit the gun over my knee to get it to open. I noticed the primers were gouged wherer the pin was stuck and the action was forced open. I talked to my dad about it after that and he said he used to hit the butt of the stock on the ground to get it to open. He didn't know why this helped, but I figure that was getting the firing pin to go back into the back of the breech where it belongs. I emailed charles daly to get a manual which will hopefuly explain how to dissasemble the action, but that will take 2 weeks to get. I was hoping someone here could direct me to a exploded view or explain to me how to get to the firing pin. I figure its either really dirty, bent, or maybe there is a spring somewhere that is supposed to return the pin ... maybe that spring is broke.
