I own a KWC 6" chrome Colt Python myself and love it. The looks of a revolver beats any pistol's look in my mind. I wasn't planning on buying a sidearm until I saw the Python because the classic pistols didn't attract me.
My baby gained it's stars by being quite silent. While playing in a forest, I managed to kill 3 people in a row within 20 feet of me before they could realize where the shots were coming from.
Tactically it's far from being as handy as a magazine-type pistol but the look compensates
