Waterfowlers will appreciate many things about the Model 1300 New Shadow Grass®. Namely, the Mossy Oak® camo finish applied to the weather-resistant composite stock, allowing this shotgun to blend in with the natural surroundings. Like all Speed Pump™ shotguns, you can count on the tough rotary bolt design to work in the nastiest conditions and, thanks to inertia-assisted pumping, you can count on it to work fast. The action and versatile WinChoke® choke system are compatible with all factory 2 3/4" and 3" magnum loads. Choose a 26" or 28" barrel.
