I purchased a LN (in appearance) Stoeger Coach Gun from a gun show for a great price, and think it has a problem. I did not want to dry fire it at the show, so I did not notice this until I got it home. After dry firing the right barrel (not a good practice I understand) the firing pin stays in the forward position. I do not notice any burrs or anything obvious, and I can (with increasing difficulty) push the pin back in. It seems to snap back in. I hosed it with non chlorinated brake cleaner (nothing) then soaked the area in break free (also nothing). Is there anything I can do to solve this, or is it for the Gunsmith? Thanks.
