The Cimarron Thunderer in .357 Magnum is a reproduction of the Colt 1877 "Thunderer" double-action revolver, maintaining historical aesthetics while offering the versatility of firing both .357 Magnum and .38 Special ammunition. This six-shot revolver features a 4.75" barrel (other lengths may be available), case-hardened frame, and blued barrel and cylinder. The Thunderer distinguishes itself from the Single Action Army design by its double-action capability, bird's head grip, and enclosed ejector housing. Notable features include the characteristic bird's head grip frame with period-correct walnut grips, traditional fixed sights with blade front sight, and right-side loading gate for cartridge insertion. The revolver maintains historical accuracy with its period-correct finishes and mechanisms while incorporating modern manufacturing techniques for enhanced durability with .357 Magnum pressures. The double-action mechanism allows for both traditional single-action shooting (by manually cocking the hammer) or double-action operation by just pulling the trigger. The Thunderer's design combines the power of .357 Magnum with the historical aesthetics of the 1877 Colt, making it popular among collectors and shooters seeking a classic double-action revolver with enhanced power.
