Our Assessment: From Wikipedia: “The Colt M1877 was a double action revolver manufactured by Colt’s Patent Fire Arms from January 1877 to 1909 for a total of 166,849 revolvers. The Model 1877 was offered in three calibers, which lent them three unofficial names: the “Lightning”, the “Thunderer”, and the “Rainmaker”. The principal difference between the models was the cartridge in which they were chambered: the “Lightning” being chambered in .38 Long Colt; the “Thunderer” in 41 Colt. An earlier model in .32 Colt known as the “Rainmaker” was offered in 1877. The M1877 was designed by one of the inventors of the M1873 Colt Single Action Army, William Mason, as Colt’s first attempt at manufacturing a double-action revolver and was also the first successful US-made double-action cartridge revolver. Neither “Lightning” nor “Thunderer” were Colt designations, nor used by the factory in any reference materials. Both terms were coined by Benjamin Kittredge, one of Colt’s major distributors, who was also responsible for the term “Peacemaker” for the Single Action Army. Old West Outlaw John Wesley Hardin frequently used both “Lightning” and “Thunderer” versions of the Colt 1877 revolver, and the Thunderer was a favorite of Billy The Kid.” This revolver is in Very Good to Fine condition for being over 100 years old, with about 70% of its finish remaining. The finish shows thinning on the left side of the barrel and pinprick surface erosion which is heaviest on the cylinder and the left side of the frame. The bore has deep rifling with very light erosion in the grooves towards the muzzle. This pistol will make a nice addition to a Colt collection or collection of antique double action revolvers. It isn’t in perfect condition, but not many are considering all are over a century old.
