The Six Shooter was a western drama radio show featuring James Stewart as Britt Ponset, a frontier drifter known for his skill with a gun. Created by Frank Burt, the show focused on the adventures of Ponset as he wandered through the wild west, often stumbling into other people's troubles and occasionally having to use his gun to resolve them. The show's tone leaned more towards comedy than other western radio shows, with episodes featuring Ponset getting involved in a variety of amusing situations, such as playing Hamlet with a crude road company or becoming involved in a Western version of Cinderella.
Broadcasting for only one season from September 20, 1953, to June 24, 1954, The Six Shooter aired on NBC and had a total of 39 episodes. The radio show was directed by Jack Johnstone and featured music provided by Basil Adlam. Notable actors that participated in the production included Parley Baer, Virginia Gregg, Howard McNear, and William Conrad. In addition to the radio show, a Hollywood Star Playhouse episode titled "The Six Shooter" was broadcast on April 13, 1952, and a TV pilot episode featuring James Stewart was created but never turned into a full series.
