You hit it right on the head. I have a 617 on order right now. I wanted an old 18 but pretty scarce unless you are willing to buy off GB sight unseen ant a pretty high price so I decided to take a chance on a new one. The new ones usually function at least.
I have 4 newer S&W revolvers. 2 have gone back on warranty, 1 has a defect but I'm living with it. #4 works fine, totally utile if not pretty.
