I bought a model 12(12 ga) that was manufactured in 1949. It's set up for trapshooting, and I've had 2 firing pins break. I don't dry fire the gun, and only use factory"AA" light target loads. Have only put 750-1000 rounds through it. Why do the pins keep breaking? Someone at another site wrote "sounds like the pin wasn't fitted properly." OK, that's alotta help! Both pins fit into the bolt just fine as far as I could tell. I assumed that they were made to a certain spec. so as to fit into the bolt without any extra "fitting" Help!
