Owners of the Cimarron Thunderball tend to appreciate the combination of the single-action format with the 9mm chambering. The birdhead grip and 3.5-inch barrel make it a more manageable carry size than a standard SAA, and the color case hardened finish draws consistent compliments for the traditional look.

The single-action trigger is generally well-regarded for its clean pull, though some owners note that the short barrel cuts velocity compared to longer SAA options. A few report that the 9mm cylinder headspacing requires moon clips depending on the configuration, which adds a step to reloading.

Value is seen as fair for a Cimarron revolver. The Thunderball sits in a niche where buyers want 9mm compatibility in a classic revolver package. Opinions on aftermarket support are mixed, as birdhead-grip SAA parts are less common than standard SAA components.
