Quadzillabill: I've had the S&W PErformance Center work over 3 of my revolvers. First was a 6.5" Model 29-2 that I carried for years until I got tired of the thing wearing a hole in my hip every time I went out into the woods with it. They installed a 4" Mountain Gun bbl, bead blasted the eniter pirece and blued it to match, and worked over the innards. She now looks like a 4" Highway Patrolman with a hellova big hole in the barrel. Had them do almost the same thing to my 6" Highway Patrolman, except they installed a 3.5 inch bbl for the Model 27, then blued the enitre thing to match and worked over the innards and man, this is one sweet lookin' and sweet shotting set of S&Ws. The third revolver they worked over for me is the Model 38 - Lightweight Bodygurad - I carry. The Performance Center smoothed the innards out just right and she is a main carry piece.
I do feel that you cannot go wrong by sending yours to the Performance center. Their work is top notch. HTH. Mikey.
