Ok, let me try again. On a rebounding hammer shotgun or similar gun, when you pull the trigger after having cocked it, the hammer falls and strikes the firing pin. Then it rebounds to a position where it doesn't rest against the firing pin. If you then push it forward (without pulling the trigger), it won't go forward enough to hit the firing pin even if it was in the full back position. On this Huntsman, you can push the hammer forward (without pulling the trigger) and the hammer will go completly forward and push the firing pin all the way in so it will set off the cap/primer. This gun wasn't designed to have a transfer bar (or if it was, a thought that just crossed my mind, it has had the hammer replaced). However, of my five Huntsman, all either have a transfer bar, or opperate in a normal rebounding hammer manner except this one. I think I have read that these old ones with the screw in breach plug were the first design, so I assume they were rebounding hammer not transfer bar design. I don't want to try to tear it apart until I have some idea what I'm trying to fix. Thanks for the help. gene
