The Cimarron Thunderer has a loyal following among single action revolver owners who appreciate the dual cylinder feature. The ability to run both .45 Long Colt and .45 ACP in the same frame is considered a practical advantage, and owners frequently mention the value of that flexibility at the range.

The color case and blued finish combination gets strong marks for aesthetics. Most buyers find the visual quality matches or exceeds expectations for the price tier. Walnut grips draw consistent praise for fit and feel. Cylinder timing is generally reported as tight and consistent.

The trigger is occasionally described as stiff straight out of the box, with some owners recommending a light action job to bring it to its full potential. Overall, the Thunderer is viewed as a well-finished single action at a competitive price, though buyers expecting a drop-in-ready trigger may be mildly disappointed.
