The Remington Model 11-87 is a gas-operated, semi-automatic shotgun introduced in 1987 as an evolutionary upgrade to the classic Model 1100. It was designed to handle a wider variety of loads more reliably, specifically allowing users to cycle both standard 2¾-inch and heavy 3-inch Magnum shells interchangeably without manual adjustments. In the 2007 film No Country for Old Men, the character Anton Chigurh uses a heavily modified Remington 11-87. This iconic weapon is a 12-gauge semi-automatic shotgun known for its massive, custom-built suppressor.
