Not nearly as good looking as Ruger's Alaskan, which is also more than 1 lb lighter. (Have Ruger & S&W switched brains?)
The whole vibe of a .460 XVR snubby seems wrong -- the .460's market niche was supposed to be a rifle-like, high-speed, long-range hunting round, whereas the .500 S&W Mag. was the heavy slammer.
Other than the prospect of using cheap .45 Colt ammo (and there are lots of lighter, more affordable short-barreled revolvers available for that) I don't see why a S&W fan would choose this gun over the .500 Mag snubby, especially now that .500 Special ammo is available. The .500 is your Smith bear stomper.
