OverWatch comes at the request of a government agency for a barrier-penetrable bullet that provides maximum hydrostatic shock with controlled expansion. Libertys use of lightweight bullets make for a low-recoiling cartridge that, interestingly, equates to high energy displacement for hard-hitting terminal performance. Plus, because of the reduced weight, more rounds can be carried onboard the operator without slowing her/him down.OverWatch is slated to come in following chamberings: 9 mm Luger, .45 ACP, .357 Mag., 10 mm Auto, .223 Rem., and 300 BLK. Handgun cartridges will feature a black-nickel-plated case and silver-colored nickel projectiles, rifle rounds are finished in bright nickel plating.
