I've seen quite a bit of different finishes on a few other forums and of course google image search. The Master blued/ Royal Blued and the copperhead seems like the more popular way to go.
I was thinking going the high polished route, bright mirror hard chrome finish on the body with black aluminum grip, then mount a ff3 on it. Done, no need to buy a $3000 nighthawk, sti, warren tactical lol
