The M1911 entered service with the US armed forces in 1911 and although it was officially replaced in 1985 with the Beretta M9, it has continued to see use with American military personnel in specialist roles due to its immense popularity. Numerous other military forces around the world have also adopted the M1911 at various points, and the South Korean Air Force still employs the weapon as officers' sidearms.
The .45 caliber handgun is famous for its simple design and high stopping power, and the ease with which it can be modified and customized have led to countless variants since its introduction, ranging from mass-produced models to bespoke pistols. M1911-type pistols can be found being used as everything from competition pistols to compact concealed-carry weapons. The Tokarev TT-33 used by Soviet Russia during WWII was based on the M1911 design.
In Predator 2, Mike Harrigan keeps several M1911 variants — two Colt Commanders (compact variants of the M1911) and an AMT Hardballer Longslide — as backups in the trunk of his police car. However, he never uses any of them, although he briefly picks up the Hardballer, before lamenting that it is "too small" and reaching instead for his cut-down Benelli M1 Super 90 shotgun.
In Predators, Royce and Mombasa both carry M1911A1s as their sidearms; Mombasa uses a stock M1911A1 while Royce's pistol is fitted with camouflage grips, Novak sights, a beavertail grip safety and a combat hammer. The dead Navy SEAL Drake is also seen with an M1911A1.
Also in Predators, Cuchillo carries a heavily customized Colt Commander. The weapon is nickel-plated and covered with engravings, and also features golden accents.
In Aliens: Colonial Marines, the M1911 serves as the basis for the M4A3 Service Pistol. The M4A3 was initially supposed to be an M1911, but the name was changed and the weapon slightly modified for the release version.
