As in most Westerns of the period, almost every character carries a Single Action Army as their sidearm.
Cavalry Model (7.5" barrel)
Wyatt Earp (James Garner) carries a Cavalry model as his primary sidearm in a black leather thigh holster while serving as city marshal of Tombstone and his subsequent vendetta ride. In real life, Wyatt Earp most likely carried a nickel .44-caliber Smith & Wesson No. 3 "American" revolver with an 8" barrel during the gunfight at the O.K. Corral.
The Artillery model is the sidearm of almost every other character in the film, including "Doc" Holliday (Jason Robards), Morgan Earp (Sam Melville), Virgil Earp (Frank Converse), Ike Clanton (Robert Ryan), Billy Clanton (Walter Gregg), "Curly Bill" Brocius (Jon Voight), Frank Stillwell (Robert Phillips), Andy Warshaw (Steve Ihnat), "Texas Jack" Vermillion (William Windom), John Clum (Larry Gates), and the Mexican soldiers at the end. Doc's model is a nickel Artillery with ivory grips, both reflecting the real life Doc's choice (a nickel Cavalry model) and making the flashy character stand out from the rest of the charaters.
