The Rifleman (1958)

S1E7 Duel of Honor

When an Italian Count comes to North Fork, his unusual clothing catches the eye of Groder, the local bully. In an attempt to amuse himself, Groder damages some of the Count's money, ridicules him, and seeks to embarrass him. Ultimately, the Count challenges Groder to a duel, asking Lucas to stand as his Second. At dawn, they gather for the duel, with the Count carrying his single-shot pistols, which Groder is not used to handling. As the Second, Lucas is responsible for ensuring that all the duel's rules are followed.
