Which Twilight Zone episode was it where the gunslinger is confronted by all the people he killed in life?

A gunslinger who is dead (but doesn't know it) goes into a saloon and somehow vaguely recognizes a lot of the people who are in there. It is later discovered that the saloon is populated by all the people he's killed in life, including one person who simply died from a stray bullet from his gun. I think it was Steve McQueen who played the gunslinger, but I could be wrong...
