Gunslinger is a 1956 Roger Corman Western with a woman as the main character and hero. The sheriff's widow is named sheriff in his place. Very unusual. It stars Beverly Garland, John Ireland and Allison Hayes. I'm not a fan. There's just a bit too much "cat fight" to it for my tastes.
She: "I'm out here disgracing Scott's memory, and it's all your fault."
