Movies like The Tin Star

Veteran bounty-hunter Morg Hickman rides into a town in danger. The sheriff has been killed, and young inexperienced Ben Owens named a temporary replacement until a permanent can be found. Ben wants to be that permanent replacement, so needs to impress the townspeople with his skill. When he finds that Morg was a sheriff for a long time before he became a bounty-hunter, he asks the older man to teach him. Morg thinks that being a sheriff is a foolish goal, but agrees to instruct Ben in handling people, more important to a sheriff than handling a gun.
