The Remington 1100 is the gas-operated semi-automatic shotgun that transformed American wing shooting when introduced in 1963. Its gas system reliably mitigates recoil — the 1100 made high-volume clay shooting and waterfowl hunting accessible to shooters who found recoil punishing. The 28-inch field barrel is the classic configuration.
