Mossberg 590 Shockwave 20 Gauge 14.38" 5+1 3" Pump - Heavy-Walled Barrel, Raptor Birdshead Grip

The Mossberg 590 Shockwave in 20 Gauge distills the legendary 590 pump-action platform into a compact, purpose-built package for home defense and close-quarters use. This 5+1 capacity model pairs a 14.38" heavy-walled barrel with a 3" chamber, giving it the reach and versatility to run both standard 2-3/4" shells and full 3" magnum loads.

At its core, the Shockwave carries every feature that has made Mossberg pump-actions the choice of millions: twin action bars, dual extractors, a positive steel-to-steel lockup, and a smooth-operating anti-jam elevator. The drilled and tapped matte blued stainless steel receiver provides a rugged, corrosion-resistant foundation that is ready for optics or accessory mounting right out of the box. An ambidextrous safety keeps operation intuitive for both right- and left-handed shooters, while the clean-out magazine tube cap makes field clearing and maintenance quick and simple.

The Shockwave's defining feature is its Black Raptor birdshead pistol grip, a uniquely contoured design shaped to minimize felt recoil and lock securely into the shooter's hand. Up front, the iconic "corn cob" strapped forend keeps the lead hand safely clear of the muzzle while providing positive pump manipulation. A bead front sight offers fast, intuitive target acquisition, and the cylinder bore choke delivers wide, even shot patterns well-suited to defensive applications.

With an overall length of just 26.37" and a weight of approximately 4.95 lbs, the 590 Shockwave is highly maneuverable in tight spaces and easy to handle from a variety of positions. Classified as fully compliant by the BATFE (the birdshead grip and overall length keep it outside Short-Barreled Shotgun NFA rules), this model requires no tax stamp for transfer.

Whether deployed as a home-defense tool or enjoyed at the range, the Mossberg 590 Shockwave delivers the proven reliability of the 590 line in a uniquely compact form factor.
