Thanks. I actually figured that out early this morning while deep in thought in my frosty outhouse here in Fairbanks. It just came to me. Have certainly used one enough as a kid. I have a bladed driver bit for a multi bit screwdriver that I ground out the center on so I could remove the striker plates on this gun that will work perfectly. I like your idea and will try it. I'd guess that this is the method they used at the factory. Thanks for the input.
