Hello. It appears that you have a very fine example of a classic S&W, one that will serve you well. Let us know how it shoots........though I think we all know the answer already! I'll bet it groups superbly.
I'm sure it'll turn into your favorite handgun. Oooo... it's got diamond grips. Nice blue. Someone took good care of it. I like the 6-shot Model 17's better than the 10-shot models with the alloy cylinder and full lug. You "done good"!
