The Cimarron Thunderer, built by Cimarron Firearms on Cimarron/Uberti tooling, brings Mike B. Harveys Model P peacemaker-style design to the Old Model (pre-1896) frame with a crisp bullseye ejector head and the compact, historically inspired birds head grip made famous by Doc Holliday; chambered in .44 WCF/.44-40 with a 4 3/4-inch barrel in this configuration, the Thunderer lineup also offers 5 1/2-inch and 3 1/2-inch barrels and caliber options including .45 Colt, .45 Colt/.45 ACP dual-cylinder, .44 Special and .38 Special/.357 Magnum to meet range, cowboy action, historical reenactment, hunting small- to medium-game, or concealed carry needs for those who prefer a shorter-barreled single-action. The standard blue finish with a color case hardened frame and hammer gives authentic period appearance while the solid single-action lockup and balanced handling make this revolver shootable and reliable under practical use; as a reproduction of the Old Model peacemaker series it sits well in a collection or as a working sidearm on the line, and note that an FFL is required for transfer.
