Gunfighter

Gunfighter and gunslinger /ˈɡʌnslɪŋər/ are literary words used historically to refer to men in the American Old West who had gained a reputation of being dangerous with a gun and had participated in gunfights and shootouts. Gunman was a more common term used for these individuals in the 19th century. Today, the term "gunslinger" is now more or less used to denote someone who is quick on the draw with a pistol, but can also refer to riflemen and shotgun messengers. The gunfighter is also one of the most popular characters in the Western genre and has appeared in associated films, video games, and literature.

Gunfighters range from different occupations including lawman, outlaw, cowboy, exhibitionists and duelist, but are more commonly synonymous to a hired gun who made a living with his weapons in the Old West.

The term "gun slinger" was used in the Western film Drag Harlan (1920). The word was soon adopted by other Western writers, such as Zane Grey, and became common usage. In his introduction to The Shootist (1976), author Glendon Swarthout says "gunslinger" and "gunfighter" are modern terms, and the more authentic terms for the period would have been "gunman", "pistoleer", "shootist," or "bad man" (sometimes written as "badman"). Swarthout seems to have been correct about "gunslinger", but the term "gunfighter" existed in several newspapers in the 1870s, and as such the term existed in the 19th century.Bat Masterson used the term "gunfighter" in the newspaper articles which he wrote about the lawmen and outlaws whom he had known. However, Joseph Rosa noted that, even though Masterson used the term "gunfighter", he "preferred the term 'mankiller'" when discussing these individuals.Clay Allison (1841–1887), a notorious New Mexico and Texas gunman and cattleman, originated the term "shootist".
