Cimarron Firearms is known for providing the U.S. market with Italian-made renditions of classic American guns that are built as historically accurate as possible while using modern practices. Not all firearms in the Cimarron lineup are reproductions though. The company’s Bad Boy is a single-action revolver built to chamber a rimless cartridge and is a blending of old, new and between. Aside from chambering 10 mm Auto cartridges, the Bad Boy is capable of hosting optics, making it a viable pistol for hunting North American big game.

The Bad Boy revolver has an 8” octagonal barrel that is fitted to a Single-Action Army Pre-War Colt 1860-style frame. The gun is crafted from alloy steel to handle the modern chambering. A color case-hardening treatment is applied to the gun’s hammer and rich blueing adorns the rest of the single-action pistol. Gloss-finished walnut stocks are provided.

A smooth cylinder is provided with the Bad Boy that has capacity for six rounds of 10 mm Auto designed to headspace on the case mouth. The cylinder is held captive by a short grooved cylinder pin. The Bad Boy is convertible to .38-40 Win. by way of simply swapping cylinders.

Sights atop the revolver consist of a square notch rear and post ramped and serrated post front. The rear sight is screw-adjustable for windage and elevation. A Picatinny rail is available to forgo traditional iron sights in favor of optics for a more precision aiming solution. Our experience on the range with the Cimarron Bad Boy pistol was a pleasurable experience. We found the blending of vintage styling and present-day features to be appealing for those looking to invest in a sidearm suitable for myriad tasks.
