I found a s&w model 17-4 with a 6" barrel today at a sporting goods store. The gun is 98 to 99% condition. They are asking $650.00 for it and will not come off the price any. Is it worth it or not? I am in the market for a da 22 revolver. I am curently looking at a new model 617 for $679.00.Which is the better buy?
