Furniture-wise, the Raptor grip is retained, since the gun requires the angled grip style to maintain a certain overall length for NFA requirements. However, replacing the corncob forearm is a chainsaw-style top grip. This style of grip is not new on Mossberg's guns, and other pistol-grip options in the company's lineup have been equipped with similar designs.
However, for the Shockwave, the grip may help shooters in the manipulation of the gun. Since the angled grip lends itself to shooting from the waist, the chainsaw-style top grip can be used to push down against recoil and offers a solid gripping point that could allow users to rack the gun by pushing the angled grip back and forward. To enhance a more-secure grip on the gun, the Mossberg Shock 'N' Saw is equipped with a strap running along the top of the grip.
Other unique features found on the Shock 'N' Saw include a new, aluminum fore-end, complete with a rail-equipped bottom compatible with Picatinny-style add-ons and accessories. The sides of the forearm are also cut with M-Lok slots for added attachment options. At the muzzle end of the gun, the Mossberg Shock 'N' Saw is outfitted with a breacher-style design and is topped with a brass-bead front sight.
Like all of Mossberg's Model 590-based platforms, the gun is equipped with a heavy-walled, cylinder-bore barrel, cut with a 3-inch chamber and equipped with a tang-mounted sliding safety. Magazine capacity tops out at five rounds when using standard, 2.75-inch shotshells. Barrel length on the Mossberg Shock 'N' Saw measures 14.375 inches long, and the overall length of the gun is 26.37 inches. Unloaded, the gun weighs 6 pounds.
The suggested retail price on the Mossberg Shock 'N' Saw is $560.
