Actually, I do own a Redhawk in .44 Mag. But it isn't my favorite, which is not listed in the poll: the Police Service Six.
I recently acquired a Police Service Six 4" blued .357 Magnum. It balances as well, or nearly so, as a 4" S&W K Frame Magnum and it costs far less. The Security Six is the same gun, but with adjustable sights, so I like them almost as much as the fixed-sight Service Sixes - I guess I just find the Service Six more asthetically pleasing than the Security Six. Both are better looking than the GP100 that replaced them though, IMHO.
I don't own a Single Six, but I'd love too. Thing is they are darned expensive in my area, and I've got a cheapie Heritage that works just fine and cost half as much. I can get the Single Six NIB cheaper (about $299) than used, as I rarely see used Single Sixes selling for less than $350 in my area. Over $400 is fairly common.
