One of the most talked-about shotguns this year has been the Mossberg 590 Shockwave—a 12-gauge, 14-inch-barreled pump-action shotgun that does not require NFA paperwork to purchase. Following the success of the 12-gauge Shockwave, the company recently announced the addition of a 20-gauge model. While both of these compact, lightweight shotguns are designed primary for home and camp defense, we think either would be just the ticket for fanning gobblers or serving as a close-range backup gun in case a coyote comes running into your lap during a calling setup.

Based on the 12-gauge pump-action 590 design, the 20-gauge version of the Shockwave required an engineering redesign. In addition to a scaled-down receiver, the cob-style, tactical fore-end was reduced in size. Weighing a mere 4.95 pounds, the 20-gauge Shockwave has an overall length of 26.4 inches and provides a 5+1 capacity.

At the core of the 590 Shockwave is Mossberg's non-binding twin action bars, positive steel-to-steel lockup, an anti-jam elevator, dual extractors and Mossberg's universally recognized, ambidextrous top-mounted safety. The lightweight receiver is constructed of anodized aluminum, and is drilled and tapped for an optic or accessories. The 20-gauge Shockwave features a 14-inch, cylinder-bore barrel and is chambered for 2 ¾- and 3-inch shells.

The Shockwave Raptor grip features a textured finish and allows for control while minimizing felt recoil. The grip is constructed of durable, glass-filled polymer with a non-reflective, black finish and an overall length of 5.25 inches. The 20-gauge 590 Shockwave has an MSRP of $455.
