The Underwood Ammo 843 Xtreme Defender 45 ACP offers superior performance for personal defense with its innovative design and high-quality materials. Based on the Xtreme Penetrator line, this ammunition features an optimized nose flute, total weight, and velocity to deliver an impressive penetration depth of up to 18 inches with a substantial permanent wound cavity (PWC). No other expanding hollow point achieves such a large diameter and volume, ensuring maximum tissue damage and stopping power. The design maintains expansion even after passing through barriers like drywall, sheet metal, or automotive glass, thanks to its solid copper construction that resists deformation and ensures consistent performance in critical situations. The nickel-plated brass casing enhances feeding reliability across various firearms, improves corrosion resistance, and maintains a clean appearance during reloading. These casings also resist tarnishing from moisture and foreign materials, making them ideal for reliable, long-term use. With a muzzle energy of 461 ft-lbs and a velocity of 1240 fps, this supersonic load provides rapid, effective responses for personal protection. The package includes 20 rounds per box, with 10 boxes in each case, making it suitable for law enforcement, security professionals, or firearm enthusiasts seeking high-penetration ammunition for personal defense. Designed specifically for centerfire handguns, the 135-grain bullet's solid monolithic copper construction combines durability and performance, ensuring deep penetration and reliable expansion in critical moments. Whether engaging threats through barriers or in open environments, Underwood Ammo's 45 ACP Xtreme Defender rounds deliver consistent, high-impact results backed by advanced ballistic technology.
