Tony,
My 617 is a fine revolver. 10 shots, stainless steel cylinder (you probably want to make sure to avoid the aluminum cylinders if you buy used, I've heard about some problmes with them), 6". I've been warming up to shoot hunter's pistol open sight silhouette with it, and it is defnitely accurate enough to do the trick, if I can hold it still and pull straight through the very nice trigger. It is heavy, however. As Brian suggested, it makes a perfect companion to a .357 686, which is why I bought mine. It's no 'kit gun', though; if you were to plan on taking it out in the field, it would be for the specific end of shooting it, not just having it along. But when you shoot it, you'll love it.
What are you looking for a .22 for, I guess is the question?
Chris
