69. The First Fast Draw Louis L'Amour 1959
Cullen Baker sits out the Civil War in Utah and comes home to Reconstructionist East Texas. He has an extant bad reputation for fighting, killing, and general malfeasance. He holds fights on 3 different fronts and finally decides to return West with the woman he's won.
The reason for his survival is a practiced lightning fast draw of a Colt Dragoon. The first of all gunfighters, hence the name.
