The Durango Kid (Charles Starrett) and his sidekick (Smiley Burnette) look for stolen gold with a history.
Western star Charles Starrett was amazing; he kept making the same film over and over, but always made it seem as if it was for the first time. In West of Sonora, Starrett once again plays a frontier good-guy named Steve (Steve Rollins, to be exact), who, when the need arises, disguises himself as The Durango Kid, masked righter of wrongs. This time, Steve/Durango champions the cause of 10-year-old Penelope Clinton (Anita Castle), who has spent her short life as the focus of a feud between her grandfathers, suspected outlaw Black Murphy (Steve Darrell) and Sheriff Jack Clinton (George Cheseboro).
Starrett tries to prevent a range war between settlers and the Native Americans. Blue and his fellow scoundrels think they can profit from the bloodshed,but the Durango Kid along with a couple of precocious youngsters put an end to Blue's terrorism.
In the lawless town of Dusty Gulch, the Durango Kid comes to the aid of Reverend Harding in his fight against Blaze Howard and his henchman. When Durango foils all bad guy's plans, Blaze's boss Doc Weston realizes Cannonball it tipping off Durango. Weston then lets Cannonball overhear false information that will send Durango into a fatal trap.
This time the Durango Kid confronts an expert gambler.
In most of his Columbia westerns, Charles Starrett simply was the Durango Kid, a mysterious masked do-gooder who pretends to be a criminal. Desert Horseman attempts to explain why this disguise has been adopted.
Quick on the Trigger was Charles Starrett's second "Durango Kid" picture for 1949. It all begins when ousted sheriff Steve Warren (Starrett) is put on trial for the murder of heroine Nora Reed's (Helen Parrish) brother. Steve is innocent, of course, but he doesn't stand a chance against prosecuting attorney Garvey Yager (Lyle Talbot) -- especially since Yager is the real killer.
Steve arrives looking for the person printing counterfeit bonds. He finds his man in Pop Ryland who has two sons and a stepson. The stepson doesn't want to be an outlaw like the other sons and helps Steve out by posing as the Durango Kid when needed and then leading him to the evidence he is looking for.
