Selleck was famous for his mustache, a Hawaiian-style aloha shirt, a Detroit Tigers baseball cap, and a Colt MKIV/Series 70 Government Model handgun (a commercial version of the U.S. Military M1911A1) which his character regularly carried. The actual prop from the show was a 9×19mm Parabellum, serial number 70L33101, used for its reliable functioning with readily available blanks, although the original gun was a traditional .45 ACP 1911. Magnum also used a Star Model B, another 9mm similar to the M1911A1, and a Detonics Pocket 9 during the series.
