Colt .45 (1950)

While gun purveyor Steve Farrell (Randolph Scott) shows off the latest revolver innovation, a Colt .45 repeating handgun, to Sheriff Harris (Alan Hale), outlaw prisoner Jason Brett (Zachary Scott) grabs a pair and hightails it out of town -- and the sheriff jails Farrell as a likely partner in crime. But during Farrell's incarceration, Brett goes on an unstoppable rampage. Farrell is released, and must stop the outlaw with the assistance of Walking Bear (Chief Thundercloud) and the Colt .45.
