The M11-87, also known as the Remington Model 11-87, is a gas-operated, semi-automatic shotgun, first announced in 1987. The weapon is based upon the Remington Model 1100. Like the Model 1100, the M11-87 has a mechanism which reduces recoil that would be otherwise present (stretching the force out over a much longer period of time than fixed-breech shotguns). The M11-87 can fire 12g and 20g, and is capable of firing most types of loads.
— In-game description
As with its counterpart, the M11-87 deals enough damage to kill two enemies at close range, and is capable of potentially dealing a large amount of damage even out to its maximum range. Its rate of fire and reload speed are both on the slower end of the spectrum, however.
- Due to the in-game weapon being pump-action instead of the real life M11-87's semi-automatic action, the weapon depicted in-game is closer to the Remington Model 870 than the weapon it is named after.
