Support Your Local Gunfighter is a follow-up to Support Your Local Sheriff and features many of the same cast members, but in different roles and situations. In Support Your Local Gunfighter, Garner plays a con man who runs away to a small Western town and is mistaken for a famous gunslinger.
A quick-witted drifter wanders into a lawless town in the midst of a gold rush. Shocked by the prices of food and meals he reluctantly takes the job of sheriff by amazing the Mayor with his lightning quick, dead eye pistol accuracy. He makes the town council know that he is really just passing through on his way to Australia and he will pull up and leave anytime he chooses (including at the first sign of real trouble). His first day on the job he takes on the biggest, meanest ranching family and meets his klutzy love interest.
Latigo Smith (Garner), a gambler and confidence man, is traveling by train in frontier-era Colorado with the rich and powerful Goldie (Marie Windsor). Goldie wants desperately to marry him, a fate he wants no part of. He sneaks off the train at Purgatory, a small mining town.
