I have a 4" 57 that is my favorite shooter -- The biggest mistake was letting go of a 6" nickel model years ago -- The 41Mag in both the police load and full blown magnum are both easy to shoot -- Accurate -- and will get any job done that can be done with a revolver IMHO
Any gunsmith worth his salt can do marvels with a S&W trigger pull -- I think S&W factory will work on them -- check with them -- I use Alex Hamilton at Ten Ring Precison for mine since he lives nearby and is very easy to deal with -- a really nice guy
I know what you are talking about -- I was just commenting on the quality Boone has shown to me -- If I was looking for revolver grips (and I have at least 40 revolvers -- mostly S&W's) I would give them serious consideration
