For your requirements I would also throw my vote to the Ruger Blackhawk, I have a few and love them. Solid as a hammer and can be carried with all 6 loaded. I prefer the 4 5/8 or 5 1/2 barrel models but this is just my preference, good luck with your hunt for your new revolver.
P.S. don't count out a nice used model, also are you looking for blue or stainless?
