Ruger SP101 Pistol, .357 Magnum, 2.5' Barrel

The Ruger SP101 is a compact, double-action/single-action revolver (often colloquially referred to by users as a pistol) renowned for its "built-like-a-tank" durability. While users often look for a 2.5-inch barrel, Ruger's actual snub-nosed standard configuration features a 2.25-inch barrel chambered in the powerful .357 Magnum. It is engineered with solid steel sidewalls and no side-plates, making it one of the strongest small-frame pocket wheel-guns ever made.
