Owners of the Cimarron Thunderer often pick it up for cowboy action shooting, and the dual cylinder that handles both .45 LC and .45 ACP is consistently called out as a practical convenience. The 3.5-inch barrel makes it compact for a single action without feeling stubby, and the case hardened frame gets praise for its looks out of the box.

The Thunderer's single action trigger splits opinion. Enthusiasts who grew up on classic revolvers find it crisp and predictable; buyers coming from modern double action guns sometimes need time to adjust to cocking the hammer for every shot. Fit and finish are generally considered good for the price point, though a few owners note minor timing adjustments after extended use.

On value, most buyers feel the Cimarron Thunderer delivers a well-made western-style revolver without premium-brand pricing. The walnut grip is a frequent compliment. Some shooters wish more holster options existed for the 3.5-inch configuration, but that complaint is more about the accessory market than the gun itself.
