10mm pistol

A Colt 6520 10mm autoloading pistol. Each pull of the trigger will automatically reload the firearm until the magazine is empty. Single shot only, using the powerful 10mm round.

10mm Pistol is a Fallout and Fallout 2 weapon. It is called a pistol, but upon resizing the image it clearly has a revolver cylinder. The 10mm pistol was in a reference to the Hard Boiled comic books. How realistic it is as a weapon is disputable.
