STR, I've read a number of reviews complaining about the 317's function (ejecting shells from cylinder) when it gets dirty. I've got to admit, it's one of the coolest revolvers I've ever handled though. What is it, 11-12 oz?
Depending what you want and how heavy you're willing to go, Taurus makes the M94 kit gun (I own the earlier M84 version) but they're heavy in SS. I like old school stuff and a Colt SAA in .22 or a Ruger .22 single action revolver are fun. That said, I only own .45 LC in that format.
