The Sheriff of Fractured Jaw (1958)

A gunsmith, a gal, and a whole lot of trouble.

English gunsmith Jonathon Tibbs travels to the American West in the 1880s to sell firearms to the locals. He inadvertently acquires a reputation of quickness on the draw due to his wrist mounted Derringer style weapon. Soon gaining the post of sheriff, he endeavours to clean up the town using what skills he has—and by multilateral diplomacy.
