Ok 1st off, any handgun with a sling swivell is officialy cool.
It shoots .454 casul .45lc and a few more.
"""We all grew up hearing the phrase, "Faster than a speeding bullet..., " but not when it is fired from Smith & Wesson's new Model 460XVR, with the highest muzzle velocity of any production revolver on earth. The Model 460XVR is so revolutionary that it required an entirely new designation...XVR, X-treme Velocity Revolver."""
so how fast is the new .460 shell?
