I carry my 617T everyday in an Uncle Mike's IWB holster....works like a charm, the weight is the same as a loaded steel J frame...Pretty good I say for seven rounds of .357! I often forget it's there.
I have just ordered a OWB beatiful belt slide from FIST holsters (who makes holsters for the 617 model exactly).
BTW...for what it's worth, I carry the 130gr Federal Personal Defense .357's....SUPER manageable recoil with about 490ft/lbs of energy. I have fired them at night, and there is almost NO flash to speak of!
I couldn't be happier with the looks and performace of the gun. Good luck in whatever you decide.
