Texas Dynamo.

Charles Starrett plays The Durango Kid in the 1950 Columbia western Texas Dynamo. As a novelty, Starrett not only plays Durango and his "alter ego" Steve Drake, but also takes on a third identity, that of a hired gun in the employ of the film's bad guys. As one critic noted, this may be the only western in which the hero is obliged to chase himself. Jock O'Mahoney -- later known as Jock Mahoney -- plays a secondary role, and also doubles for Starrett during the riskier stunt sequences.
