Didn’t John “Westley” Hardin use one of these?
No, Wyatt Earp at at the OK Corral.
Apparently worked effectively, or at least the promptly-deceased Billy Clanton and Frank McLaury would say so.
Correction:
Hardin preferred it, as did Jessie James and Wild Bill Hickok.
I live in Lincoln County, NM, so I best get this weapon.
John Wesley Hardin used a S&W American model to shoot Shriff Webb. Hardin used more types of revolvers than any other outlaw in the Old West. Whatever he could get his hands on. In 1877, well into the cartridge era, when arrested he was carrying an 1860 Colt Army cap and ball revolver.
