The S&W 460 is built on S&W’s largest frame, the X-Frame, which was developed because none of S&W’s existing double-action frame designs could handle the muzzle energy and pressures generated by the .500 S&W cartridge.
The .460 S&W Magnum is essentially a longer and more powerful version of the .454 Casull, itself a lengthened and more powerful .45 Colt. Able to push a 200 grain bullet past 2,300 fps, the .460 S&W is not just one of the most powerful handguns in the world. It also fires at one of the highest velocities of any revolver in the world, allowing for unprecedented penetration when hunting with a revolver. This example is the Emergency Survival, or ES, model and comes with its emergency kit. (I can’t even imagine what the report & recoil must be like on this mighty midget of a gun!)
