Overall Condition: This revolver retains about 85% of its metal finish. There is some finish loss at edges and scattered spots of surface oxidation through the finish. Some areas have a cloudy appearance, but most remain fairly shiny. There are some scattered light nicks, scuffs and scratches. The action shows operational wear. The markings are generally clear, some are worn, but legible. The screw heads range from sharp to tool marked with strong slots. Overall, this revolver is in Fair-Good condition, as refinished Antique (see Mechanics).

Mechanics: The hand spring appears to be missing or broken. The cylinder advances properly when the revolver is pointed down and does not advance when pointed up. Otherwise, the action functions correctly. The cylinder locks up with little play. The double action trigger is fairly smooth. The single action is crisp. We did not fire this revolver. As with all used firearms, thorough cleaning may be necessary to meet your maintenance standards.

Box, Paperwork, and Accessories: None.

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 good for its age, retaining much of its nickel finish at more than 130 years old and apart from an issue with the hand spring, the mechanics are strong. This would be a neat addition to a Colt collection, especially one missing the “Thunderer”. Please see our photos and good luck!
