Inertia Driven^®System

Benelli’s Inertia Driven® System is a simple, proven operating system engineered for exceptional reliability in demanding conditions. Using the firearm’s recoil energy to cycle the action, the system requires only three primary components—the bolt body, inertia spring, and rotating bolt head—resulting in a clean, efficient design with fewer moving parts.

Because the system operates without redirecting gas into the action, heat, carbon, and fouling are kept to a minimum, helping the firearm run cleaner and reducing maintenance requirements. The result is fast, consistent cycling, dependable operation, and the durability law enforcement professionals expect from Benelli.
