"The Law of Inertia"

“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 of physics in the Inertia Driven^® system to operate the world’s fastest, simplest and most reliable semi-automatic shotguns. It’s not boasting, it’s the law—The Law of Inertia.

The Best Operating System Ever Devised

Reliable—The Inertia Driven^® system never needs adjusting and will cycle anything from light field loads to 3-1/2" magnums with consistent reliability, year, after year, after year. In fact, there are Inertia Driven^® Benelli shotguns that have fired over 500,000 rounds, still in the field and functioning perfectly.

Simple—Inertia Driven^® is simple with only three primary parts: the bolt body, the inertia spring and the rotating bolt head. Simple is better.

Cleaner—Gas, smoke and burnt powder stay in the barrel where they belong, rather than being channeled into the gun’s mechanism, as they are in gas systems.

Strong—The strong steel locking lugs on the Inertia Driven^® system’s rotating bolt head not only lock steel-to-steel into the gun’s barrel; the lugs lock in even tighter during firing.

Faster—With a greatly reduced mass of parts, Inertia Driven^® is faster.

Low Maintenance—The Inertia Driven^® system is much cleaner so gun cleaning takes a fraction of the time that it takes to clean a gas-system gun.

Lightweight—The Inertia Driven^® system is not only incredibly simple, it is also lightweight, allowing Benelli shotguns to be some of the lightest semi-automatic shotguns ever produced.

Perfect Balance—With no springs, action bar linkage or heavy gas cylinder under the forend, Benelli’s Inertia Driven^® shotguns balance like a fine game gun should.
