Somehow the cross pin that keeps the firing pin in place is stuck. I just changed the firing pin and while reinstalling the cross pin I noticed it was very difficult to hammer back into place with my drive punch. Well I keep hammering at it until it was in place and now I cannot remove it. I already ordered a new cross pin which is on the way, but does anyone have any suggestions on how to remove it? I already tried heating it up which did not help. Any suggestions welcome.
