What type of operating system do the Benelli and Beretta shotguns utilize?

The Benelli and Beretta shotguns utilize a recoil or inertia operating system, which is a distinctive mechanism that uses the energy generated from the recoil of the shotgun itself to cycle the action. This system effectively allows the shotgun to automatically eject the spent shell and chamber a new round after firing.

In the case of the Benelli shotguns, the inertia system is particularly notable because it relies on the mass and momentum produced by the recoil to engage the bolt mechanism, which leads to a faster and more reliable cycle than some other systems. This means that the shotgun can operate smoothly even with a range of ammunition types, including lighter loads that might not function well in other operating systems.

The design and mechanics of inertia-recoil systems contribute to fewer moving parts compared to gas-operated systems, resulting in less maintenance and reduced weight, making these shotguns highly favored for tactical and competitive applications. Users often appreciate the reduced recoil and improved handling characteristics provided by this operating system, enhancing overall shooting performance.
