Stoger's M3500 series of shotguns delivers quality and performance at an unbeatable price. These ultra-reliable semiautomatic shotguns are equipped with Stoger's proven Inertia Driven System - a simple yet reliable action that differs from gas-operated semiautomatics. The Inertia Driven System is composed of just 3 moving parts and eliminates the need for gas cylinders, O-Rings, and other complicated parts. Instead of using gas expansion, the Inertia Driven System uses recoil to cycle shells. This allows the M3500 to handle a massive assortment of different loads from light 2 3/4" cartridges to 3 1/2" magnum shells. The Inertia Driven System also keeps the action cleaner since all the gas and burnt powder are expelled through the barrel.
