Firing pin problem on Stevens 22 & 410
This is my first posting so hope don't screw up. I just inherited my dad's Air Force survival gun. Remember as a kid sneaking it out to shoot with friends. Also remember the 410 firing pin broke. I could still shoot it pointed up in the air but just not when held at level position. Anyone know if it sounds like I need a new firing pin or just a spring? The 22 pin seems to be held in place and has on-going pressure but the 410 pin doesn't seem to have the same pressure on the plate which returns it into place.
