One of the hottest firearms introductions of 2017, announced at the SHOT Show in Las Vegas, was undoubtedly the Mossberg 590 Shockwave, which was originally chambered in 12 gauge. Right on its heels came Remington with the 870 Tac-14, another wildly popular defense shotgun, and yet another confirmation of the worth of a compact shotgun that can be had without climbing a Mount Everest of bureaucratic red tape.
The genius behind the Shockwave is that it features a 14-inch barrel but avoids NFA classification since it is produced from the factory with a pistol grip and is above 26 inches in overall length. Same great performance from the 590 build, now in a compact package that’s ideally suited for personal defense situations.
In the fall of 2017, Mossberg extended the Shockwave to include a 20-gauge variant. In design, it is identical, with the obvious exception of shell selection, and features the Shockwave Technologies Raptor grip. Overall length is 26.37 inches, with a 14-inch barrel and 5¼-inch pistol grip. The cylinder bore accommodates shells in 2¾- and 3-inch loads, with an overall capacity of six shells. As a 590, the shotgun features a thumb safety with red indicator and a slide lock release lever at the rear of the trigger guard.
