I'm trying to do a F&B on my new P32. I have the hammer spring released but can't for the life of me get the frame pins out. I've tried everything I can think of and am starting to damage the pins. I have a punch and a block with a hole in it, but no matter how hard I try those suckers will not come out. I don't want to damage them and not be able to get the gun back together. Any ideas?
