Mossberg has introduced a .410 variant of their popular Shockwave 590 shotgun which joins the 12 and 20 ga models already on the market. As you may recall, the Shockwave is classified as a “firearm” under the Gun Control Act Of 1968 which means its dimensions of 14.73″ barrel and overall length of 26″ aren’t considered a short barrel shotgun.
