The Night Rider(1920)

Texas Guinan is having her cattle rustled, so she head into town to hire a night rider. While her one employee is checking out Pat Hartigan, she overhears someone say she needs a husband to manage the ranch. So she pulls out a gun, orders the new preacher over, and marries him at gunpoint, which he doesn't object to. When Hartigan comes over, she opines she's married the wrong man, but facts are facts.
