Our Assessment: 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 Long 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. This Thunderer looks like it has seen a fair amount of use in the last 131 years, but retains serial-matching parts, a relatively decent bore for its age and good mechanics. Regardless, this would be a great addition to a Colt collection. Please see our photos and good luck!
