Sledge Hammer! (1986)

Season 1: Episode 4

An escaped convict wrecks havoc in the city, promising even more destruction unless Hammer agrees to meet him in an old west style showdown. The convict is John Kogan, Hammer's childhood rival as well as former partner in the police department. Kogan is also the only man faster on the draw than Hammer… a fact that Sledge is well aware of.
