There’s less training conducted with the defensive shotgun than with any other defensive firearm. This is partly because shotguns recoil the hardest, and recoil is not something shooters typically enjoy. It’s also partly because shotguns—at least compared with handguns and carbines—are a bit expensive to shoot, especially if you’re training with 00 buckshot.
Federal has introduced a .380 ACP load to its Hydra-Shok Deep lineup, the first cartridge for the chambering to consistently meet FBI protocol recommendations for penetration—12 inches minimum—through bare gel and through heavy clothing.
Federal proves you can achieve optimal performance for self-defense without the kick.
