Underwood Ammo Xtreme Defense Platinum 9mm Luger 68gr Solid Monolithic – 20 Round Box

The Underwood Ammo Xtreme Defense Platinum in 9mm Luger delivers next-level terminal performance engineered for those who demand the best in self-defense ammunition. Built on the proven Xtreme Penetrator platform, the Xtreme Defense features an optimized nose flute design that drives penetration up to 18 inches while producing a Permanent Wound Cavity (PWC) reported to exceed 100% greater diameter and volume than traditional expanding hollow points.

The 68-grain solid monolithic copper projectile maintains structural integrity through common barriers including wallboard, sheet metal, and automotive glass — ensuring consistent, reliable terminal performance regardless of the threat environment. Unlike conventional hollow points that can clog or fail to expand after passing through intermediate barriers, the Xtreme Defense geometry delivers devastating hydraulic displacement on impact without relying on expansion.

Each round is loaded in nickel-plated brass casings, offering superior corrosion resistance over standard brass, enhanced feeding reliability across all action types, improved cosmetics, and easier cleanup during reloading. Nickel plating also resists tarnishing during storage and when exposed to leather, moisture, and other metals — keeping your carry ammunition looking and performing like new.
