This is a great example of an original Colt Sheriff’s Model 1877 "Thunderer" double action revolver. The pistol is chambered in .41 Colt, attributing it to the nickname "Thunderer", given to the revolver by Colt distributor, Benjamin Kittredge—who also nicknamed the Peacemaker, Lightning, Rainmaker, and the Frontier model. The Model 1877 was the first successful, US made double-action cartridge revolver conceived by the same designer of the famed Colt Single Action Army, William Mason. This revolver in particular features a patina nickel finish, hard rubber birds head grips, 3 ½” barrel, and a cartridge ejector. The revolver shows matching serials, which date the manufacture of the revolver to 1880. Additionally, the revolver is marked with the trademark rampant colt logo on each side of the grips. The left side of the frame is also marked "PAT.SEPT 19. 1871 - " " 15. "74 - ' JAN 19. "75". The left side of the trigger guards reads ".41 Cal". The top of the barrel reads "COLT'S PT F.A. MFG, Co. - HARTFORD. CT. U.S.A". The revolver is in good condition with wear indicative of age, showing holster wear, and wear from usage. Serial Number: 22755. This firearm qualifies as an Antique, and does not require FFL Transfer or NICS Background Check.
