I gave my son a Marlin 795 (maybe 797?) that I'd hardly ever shot. It's the one with the bull barrel and black tupperware stock. Anyhow he called me yesterday as he was up in the desert out in Cali shooting with a buddy and he said it would chamber a round and go to battery but would not fire even with the safety positively off. He said the trigger just would not pull. It's definitely not a mag problem so what ya'll think? firing pin issue, trigger sear, something else? I did a bit of googling and couldn't really find much.
