In this volume, Eugene Cunningham collects - in his "gallery" - biographies of nearly a score of master gunfighters, including such notables as John Wesley Hardin, Billy the Kid, Dallas Stoudenmire, Sam Bass, Wild Bill Hickok, Butch Cassidy and Tom Horn. His final chapter, "Triggernometry", remains an interesting discussion of the gunfighters' expertise with the fast draw, the "road-agent's spin", pistol fanning, the "border shift", "rolling" and "pinwheeling", and the use of various holsters and harnesses. This new edition includes an extensive introduction and updated bibliography by Joseph G. Rosa. Discussing in detail the types of pistols used by the gunfighters, their speed and accuracy in gunfights, and the qualities of a deadly gunfighter, Rosa also provides new information on many of the more prominent gunfighters in Cunningham's gallery.
