I decided to swap out the aluminum grip frame on a NM Blackhawk for a steel one I had lying around. Simple enough a few screws and it's done, right? Wrong I can't seem to get it back together so it works correctly. The transfer bar is catching on the firing pin.GRRRRRRRRRRRRRRRRR!!!!!!!!!!!!!!!!!!!!!!

the transfer bar when completely inserted.

I'll do that. Thanks.
