Hi, all. I was looking thru Brownells and found that the wide, low superblackhawk hammer was listed as a SBH part, but all other parts seemed to be common parts. Does this mean I can convert my NM Blackhawk to a SBH hammer just with the hammer? Or would other parts need replaced too? And of course, if someone has done this conversion, does the hammer fit the slot in the frame, etc, or is it a big job I should forget about attempting?
