### Detailed Features
The inertia-driven piston system cycles quickly between shots and keeps felt recoil lower than gas-operated designs of similar weight. At 7.1 lbs with a 28-inch barrel, the balance works well for both hunting and clay shooting.

The 5+1 capacity gives a full magazine for most hunting situations. The black parkerized finish resists corrosion and wear, and the walnut stock adds some traditional character to an otherwise modern platform.

### Usage
The Matrix Inertia handles a variety of roles from waterfowl to upland game to sporting clays. The inertia system is generally reliable with both light and heavy loads once broken in, and the walnut furniture keeps the gun from feeling purely utilitarian.
