Following the ground‐breaking introduction of the 12‐gauge 590 Shockwave in 2017, Mossberg has continued to expand the line-up with a 20‐gauge offering, and additional 12‐gauge models including the 590 JIC® (Just In Case) Shockwave. This announcement comes just months after TFB’s Nicholas C’s Mossberg coverage at GAOS.

Now Mossberg delivers the ultimate lightweight and low‐recoiling home defense platform with the announcement of the 590 Shockwave in .410 bore. This compact firearm features a 14‐inch barrel length; Raptor® pistol grip; strapped forend; impressive 6‐round total capacity; and weighs in at a mere 4.24 pounds.

Built on Mossberg’s proven pump‐action design, the 590 Shockwave features non‐binding twin action bars; positive steel‐to‐steel lock‐up; an anti‐jam elevator; dual extractors; and ambidextrous top‐mounted safety. The 590 design also includes an anodized aluminum receiver, drilled and tapped for ease of adding optics, and magazine tube with convenient clean‐out cap.

About the Mossberg 590 Shockwave

The .410 bore offering is 2 ½ and 3‐inch capable; features a 14‐inch heavy‐walled, cylinder bore barrel with single bead sight; and sling swivel studs. The Shockwave Raptor pistol grip, constructed of durable polymer, has an enhanced textured finish and “bird’s head” shaped‐profile, allowing for greater control while lessening felt recoil.

The cob‐styled, synthetic forend is strapped for safety, greater control and smoother operation. The grip and forend feature a black finish and exposed metalwork has a complementing matte blue finish.

With an overall length of 26.37 inches, the BATFE (Bureau of Alcohol, Tobacco, Firearms and Explosives) has classified this compact 590 Shockwave platform as a “Non‐NFA Firearm,” requiring no tax stamp for transfers. Defined as a firearm, not a long gun, Federal Law does require the purchaser of the pistol grip 590 Shockwave to be 21 years of age.

Mossberg was the first manufacturer to bring these 14‐inch barreled, non‐NFA firearms to the marketplace and now offers three 12‐gauge models, a 20‐gauge option and the new .410 bore from which to choose.

Disclaimer: Although the Mossberg 590 Shockwave is classified Federally as a “firearm” under the Gun Control Act of 1968 (GCA), and is not subject to the provisions of the National Firearms Act (NFA), state and local laws may be more restrictive. Although it is legal federally, the 590 Shockwave may be considered a “short‐barreled” shotgun or “assault weapon” by certain state and local laws; and therefore illegal to possess.
