Smith & Wesson Model 500

=Smith & Wesson Model 500= The Smith & Wesson Model 500 is a five-shot, single action/double-action large caliber revolver produced by Smith & Wesson, firing the .500 S&W Magnum cartridge, a .50 caliber bullet.

It 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. It is the most powerful production revolver in the world today, and it is being marketed as being "the world's most powerful handgun" by the manufacturer. There are a few larger revolvers, like the Pfeifer Zeliska .600 Nitro Express revolver, however none of them are a "production" revolver. The Model 500 can fire a bullet weighing 350 gr ( 22.7 g; 0.8 oz) at 1975 feet per second (602 m/s) generating a muzzle energy of over 3,030 foot-pounds force (4.1 kJ).

The 4 inch version is the one Peter Baker  has used to kill the Freon Nightmare -  and is still carrying this weapon.
