Inertia Driven System Logo

Benelli’s Inertia Driven® system, developed in 1967, operates cleanly and reliably without adjustments.


Inertia Driven System® is the original version of the best operating system ever devised. There are Inertia Driven® Benelli shotguns that have fired 500,000+ rounds and still function perfectly.

The Inertia Driven System is a reliable and easy-to-use system that can handle a wide range of loads - from light field loads to heavy 3-1/2-inch magnums. It's simple to operate and only has three main parts, which makes it easy to clean and maintain. The system is very strong and is made with durable steel locking lugs on a rotating bolt head. It's fast and lightweight, and perfectly balanced which makes it easy to carry and use.
