I had one of those in my hands last weekend and I was very impressed the way it was made and its looks. When I swing the cylinder out, I realized it is a 6 shooter +P 38 Spc. I want one now! I would ove one in a 3" configuration though.
As far as fitting the holster, it looks and feels the same as the 5 shooter revolver. Not much noticeable difference.
