Underwood Ammo 815 9mm Luger Xtreme Defender 90-Grain Monolithic Solid Copper Personal Defense Rounds

The Underwood Ammo 815 9mm Luger Xtreme Defender is engineered for maximum penetration and stopping power. Designed based on the Xtreme Penetrator product line, these rounds feature an optimized nose flute, total weight, and velocity to achieve an impressive penetration depth of up to 18 inches with a permanent wound cavity (PWC). No other expanding hollow point delivers such a large and consistent wound channel, making this ammunition ideal for personal defense scenarios. The solid copper construction ensures that barriers like drywall, sheet metal, and automotive glass do not diminish the bullet's effectiveness, maintaining its deep penetration and cavity volume even after passing through obstacles. The nickel-plated brass casings offer enhanced feeding reliability across various firearms, along with improved corrosion resistance, a cleaner reloading process, and better cosmetic appearance. These casings resist tarnishing during storage and contact with moisture, leather, or other metals, ensuring long-term durability and performance. With a supersonic muzzle velocity of 1400 fps and muzzle energy of 392 ft-lbs, this 90-grain round delivers rapid and reliable energy transfer, making it a trusted choice for personal defense. Each box contains 20 rounds, with 10 boxes per case, providing ample ammunition for reliable self-defense readiness.
