When Louis Winthorpe III (Dan Aykroyd) is forced to sell his expensive watch in a pawn shop for $50, he looks down and sees a Colt Commander with pearl grips. He asks how much and apparently is sold the gun! In real life, without a pistol liscense or any money, buying a handgun proves somewhat troublesome. Winthorpe then takes it with him to the Christmas party and threatens to kill Billy Ray before running away. He tries to commit suicide with it but the gun misfires. He tosses it away and the gun hilariously goes off.
When Winthorpe and Billy Ray join together to take down Randolph Duke (Ralph Bellamy) and Mortimer Duke (Don Ameche) for wrecking their lives with a simple bet, Winthorpe takes out several 12 Gauge Double Barreled Shotguns and loads them up.
Clarence Beeks (Paul Gleason) draws a Walther PPK on Winthorpe when he realizes he is in disguise and holds it on Ophelia (Jamie Lee Curtis) before he is knocked unconcious by a cage gorilla and has it taken away by Coleman.
