When it comes to home-security firearms, a simple-to-operate, dependable firearm in a crisis can make a world of difference. For that reason, Mossberg 930 Special Purpose autoloaders are finding their way into more homes as a primary defense firearm. All Mossberg 930 Special Purpose shotguns feature a self-regulating gas system that vents excess gas to aid in recoil reduction and eliminate stress on critical components. All 930 autoloaders chamber both 2 3/4 inch and 3-inch 12-gauge shotshells with ease--from target loads, to non-toxic magnum loads, to the latest sabot slug ammo. This modle features ghost ring sights and a 7+1 capacity.
