I too have a 617SS. I love the gun and carry it daily with a Galco FLETCH holster. I carry it with .38+P JHP's. .357 is a bit too much for me without more practice.
Anywho, a quick question for ya. I would love to get some ribber grips for mine. Where did you get yours? I have a buddy that has a Judge, and I really like those ribber grips. After I shoot about 100 rounds of .357 out of mine, it feels like someone hit me in the hand with a baseball bat.
