In the Alternate 1985, Biff Tannen (Thomas F. Wilson) pulls a Smith & Wesson Model 60 with 2 1/8" barrel and rubber grips on Marty McFly (Michael J. Fox) after explaining how he came to be so rich.

Biff then corners Marty on the roof with the Model 60, stating he was the one who killed his father, with the same Model 60 - "Two McFlys with the Same Gun," he says.
