I can't find any parts for my m19-3 but I read in a post that the m66 is a stainless 19. I se lots of parts for the 66 and other k frames at numerichs. Does anyone know which parts will interchange? Thanks
As long as the hammer nose you got is pre-1988 (when S&W changed the hammer nose to include a spring) you should be fine. Post-1988 hammer noses are different.
