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.

Charles Starrett once more dons the mask of mysterious do-gooder "The Durango Kid" in Columbia's Challenge of the Range. Wandering cowboy Steve Roper (Starrett) is hired by the Farmers Association to stem the activities of a group of gunmen who are driving ranchers off their land. The most likely suspect turns out to be innocent: the real culprits are within the Association itself. With the help of the chief suspect's son, Roper brings the crooks to justice.
