Keep in mind the S&W's, especially the 617, have plenty of parts and other goodies available as well as being time-tested. Different sights, grips, springs, replacement parts, etc are all out there. I have a 617 and my only complaints are the basic sights are 'meh' and the trigger, because it was nearly NIB when I got it, needed a little smoothing out. A few minutes with an emery cloth and a couple drops of oil and I was good to go. Now I'm just looking around at different options for sights, some wooden grips, and lighter springs.
