Benelli offers the largest selection of semi-automatic shotguns in the world; no other company even comes close. The "Law of Inertia" is Newton's first law of physics and is as consistent and unchangeable as the law of gravity. Benelli has harnessed this basic law in the Inertia Driven™ System to operate the world's fastest, simplest, and most reliable semi-automatic shotguns. Their guns have been manufactured in Urbino, Italy, by the Benelli Armi Society since the 1960s.
