There is no more durable, reliable pump shotgun than a Model 1300 Black Shadow. The non-glare matte finish of the barrel and receiver won’t give away your position to wary waterfowl and the durable composite stock and forearm are up to any abuse a day afield can dish out. The hard working Speed Pump action fires all factory steel, tungsten, bismuth and lead shot compatible 2¾" and 3" magnum loads. Available in both 12 gauge and 20 gauge models. A 12 gauge model is also available as a combo that includes both a rifled barrel and a 28" vent rib field barrel.
