Gun Test: Mossberg M590 Shockwave

In the typical home, entering doorways (a.k.a. “fatal funnels”) and “slicing the pie” with a 24″ to 28″-barreled shotgun reduces maneuverability, escalates exposure and, at corners, increases the likelihood of the barrel being seized by an intruder. With its M590 Shockwave, Mossberg offers a unique solution to these shortcomings by minimizing both the gun’s barrel and overall lengths.

Distinguishing the M590 Shockwave from its Model 500-series shotgun counterparts are interrelated features that improve its suitability for home defense, as well as change its designation with the Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE). Replacing the traditional buttstock is a polymer Shockwave Technologies Raptor bird’s head-style grip that adjoins a bead-sighted, 14 9⁄16” cylinder-bore barrel. The result is a 12 gauge with a short, 26 11⁄16” overall length.

According to a letter from Michael R. Curtis, chief, firearms technology industry services branch of the BATFE to Mossberg, dated March 2, 2017, “The weapon [Shockwave] … is a ‘firearm’ subject to GCA [Gun Control Act of 1968] provisions; however, it is not a ‘firearm’ as defined by the NFA [National Firearms Act].” He added, “Please note that if the subject firearm is concealed on a person the classification with regard to the NFA may change,” as well as, “If the design, dimensions, configuration, method of operation or materials were changed [from the sample submitted], our determinations would be subject to review.” This doesn’t account for state or local restrictions.
