I have the S&W model 17, with the 6 inch barrel. I believe it is the same as the 617, but mine is blued and not stainless. Mine has the 6 round cylinder.
I bought mine lightly used, complete with box, for $250.00. I don't believe it was ever fired.
It is a nice revolver. The double action trigger pull seems very heavy. I usually fire it single action. I was thinking about installing Wolf spring kit. I have can hold a six shot group within 1 inch at 50ft, using iron sights. I noticed my groups got tighter when I traded the stock wood grips for Hoage rubber finger-groove grips.
If I was going to buy a new one, I would buy the ten shot model.
I do not fire this revolver much, as I prefer my model 41. I feel the .22LR revolver is the perfect trainer for anyone getting into handguns. I also have a model 48, which is the same revolver in .22 magnum.
