The Remington 1100 was the first semi-automatic shotgun designed from the ground up to reduce felt recoil through a gas-operated action, making it instantly popular with clay target shooters and hunters. Its gas system bleeds pressure from the barrel to cycle the action, reducing perceived recoil by approximately 25 percent compared to recoil-operated guns of its era.
