I rarely, as in almost never, buy new guns. With S&W, and most other manufacturers, the older they are the better I like them. The pre 17s/18s and their later model number versions are perfect. That said, I have a no dash four inch 617 that may just be the best of the bunch from a purely fun shooting perspective. And last year I found a 10 shot 617-6 Mountain Gun (ok, made in 2012 even though they didn't show up until last year, so not really "new" but close enough) and it is as well made and fun to shoot as the no dash or the earlier guns for that matter. That's a long ramble I guess to endorse your inclination to buy a new 617. Enjoy.
