The Mossberg 590 Shockwave Shock’n Saw is a 12 gauge pump-action firearm built on a 14.375-inch barrel with a 3-inch chamber (brand part no. 50647). It is the Shock’n Saw configuration of the 590 Shockwave, the compact, stockless pump gun that Mossberg built for close-range work. The tubular magazine holds five shells with one more in the chamber, and the gun runs the ambidextrous top-tang safety that 590 owners already know. A front bead and a cylinder bore choke keep the setup simple for buckshot and slugs at room distances. At 30.65 inches overall, it suits shooters who want a short, handy 12 gauge for the truck, the ranch or the house.
