Owners of the Cimarron Bad Boy gravitate toward it as a hunting or outdoors sidearm. The 10mm chambering in a single-action revolver is an unusual pairing, and most buyers are specifically seeking that combination for use in the field where a hard-hitting handgun round matters. The 8-inch barrel is a draw for velocity and sight radius.

The included .38-40 cylinder is a conversation piece. Some owners say it adds practical value, giving them a second caliber option in an older cartridge. Others rarely install it and treat the extra cylinder as a novelty. The target sights get consistent positive comments from buyers who find standard single-action sights inadequate for the distances they want to shoot.

Build quality opinions on Cimarron revolvers tend to be favorable. The Bad Boy's trigger is described as typical single-action, with a clean break. A common point of criticism is the price versus comparable imported single-action revolvers, with some owners feeling the dual-cylinder configuration justifies the premium while others disagree.
