The Cimarron Thunderer in .45 Colt is a reproduction of the classic Colt Model 1877 "Thunderer" double-action revolver. This six-shot revolver features a standard 4.75" barrel (also available in 3.5" Sheriff's Model and 5.5" versions), case-hardened frame, and blued barrel and cylinder. The revolver distinguishes itself with its characteristic bird's head grip frame fitted with period-correct walnut grips, enclosed ejector housing, and double-action capability. The unloaded weight ranges from approximately 36 ounces with the 3.5" barrel to 42 ounces with the 5.5" barrel. Notable features include traditional fixed sights with a blade front sight, right-side loading gate for cartridge insertion, and period-correct finishes. The double-action mechanism allows for both traditional single-action shooting (by manually cocking the hammer) or double-action operation through a longer trigger pull. The .45 Colt chambering provides substantial power while maintaining historical authenticity to the original Thunderer design. Additional features include precision-machined parts, hand-fitted actions, and authentic details like the period-correct timing mechanisms. The combination of the powerful .45 Colt cartridge, historical aesthetics, and double-action capability makes this model particularly appealing to collectors and shooters seeking a classic double-action revolver with significant stopping power.
