(This bit on shotguns is from a much longer article titled GUNFIGHTERS OF THE OLD WEST by Norman B. Wiltsey that appeared in the 1967 Gun Digest)
It is most enlightening to the researcher in Western Americana to discover that the unglamorous but deadly efficient shotgun played a far more important role in the taming of the West than the writers of the Draw, you varmint! school of scribblers care to admit. Tough John Slaughter, Sheriff of Cochise County, Ariz., in the late 80s put a reporter from a New York newspaper straight on the matter in short order. Somehow the dude scribe got up the nerve to ask Slaughter why he carried a shotgun along with a Winchester 44-40 and a Colt 44 revolver on his manhunts.
Johns hard black eyes narrowed in contempt. To kill men with, you damned fool! he snapped.
Which simple, cold fact explains why so many gunfighters on both sides of the law, packed the lethal scattergun as an essential tool of their dangerous trade. At long range, of course, there was no substitute for the rifle, so John Slaughter, Wyatt Earp and many others packed shotgun, Winchester and six-shooter.
The great advantage of the shotgun to the average man was that with it he was equal often superior to the professional gunslinger. Shotguns fired by ordinary citizens broke up the James-Younger gang in the Northfield, Minn., bank robbery, and in Trinity City, Texas, John Wesley Hardin, who gunned down 44 men during his bloody career, came within inches of death by a scattergun in the hands of Phil Sublet. Hardin pulled through because of a heavy, gold-laden money belt that stopped most of the charge of buckshot, but he was out of action for several months.
Stagecoach guards carried sawed-off shotguns in addition to rifles and revolvers, and the phrase riding shotgun became an indelible part of Western vernacular and legend.

Other historical encounters involving a shotgun that come to my mind include:
Doc Holliday at the OK Corral
Wyatt Earps reported termination of Curly Bill Brocious
Billy the Kid takes out Bob Olinger
"Killer" Miller's weapon of choice on numerous occasions
Would like for readers to post accounts where a scattergun played a prominent role in other Old West "dispute resolution".
