5.5" Redhawk
I have had three of these over the years, most recent one is a 5.5" blue- and it's a keeper. I shoot loads ranging from Garrett-level 300s to 200-grain small game loads at 800 fps, and I haven't moved the rear sight to accomodate either. How? Take the tallest front sight you can find and sight in with your heaviest-bullet load. Take another front sight and 'file it on' for your light-bullet load. This will take a lot of patience, and you may have to file a little off one side of the second sight to regulate the windage (they are not all exactly alike for thickness, etc.) but when you're finished you can hunt anything from chipmunks to moose without changing anything except the rounds in the cylinder, and the front sight.
I haven't had a Dan Wesson in years, but the .357 I had back 25 years ago didn't impress me much- other than the finish. It was a beautiful gun.
If you go with the Redhawk, try a set of Butler Creek rubber grips for this model. Softest-shooting grips I have found in 20 years of handgunning with these fine revolvers.
Good luck-
