The S&W model 19 2 1/2" in blue is the best looking revolver out there. That being said I sold mine and have a model 66 in 2 1/2" as I shoot the snot out of my guns. It looks like the day I bought it. I live in Arizona where rust isn't much of an issue, but bluing loss and holster wear due to dusty conditions is. As you can't go wrong either way, my vote is for the model 66.
