Thanks, everyone!
Shrek of the Arctic, not at all! I want the best revolver that works for me and, as much as I like my 649-5 snub nose (the trigger pull is REALLY long and the front sight moves a lot when I pull the trigger), I'm totally open to another brand that might help me best.
In fact, when I was at my LGS yesterday, the owner tried to sell me his Ruger LCR, 5 shot. The trigger was VERY smooth and my front sight barely, if at all, moved. I believe it was the 3" version. He threw out $450+ for a private party transfer. Any thoughts on that revolver and the deal? Or would my 649-5 with its challenging trigger pull accomplish the same or more?
It also turned out my LGS only has the 6" version of the 617, and the seller of the 4" 617 never got back to me about the deal.
Newbie question: other than a 2" barrel and longer sight radius, are there any other differences for my purposes (again, I'm not going to carry/holster it, just use it to improve marksmanship, particularly trigger control).
OTOH, I have a S&W Model 649-5, and wonder whether I can accomplish the same and save money ($1,000 M617 vs. .38SPL ammo?)?
