The Remington 1100 is one of the most successful semi-automatic shotguns ever produced, with over four million units sold. Introduced in 1963, it uses a fixed-piston gas system that effectively dampens recoil, making it one of the softest-shooting semi-autos of its era. The 28-inch Field configuration remains in production in a classic form.
