The Underwood Ammo 864 Xtreme Defense 9mm Luger +P 68gr Solid Monolithic round is engineered for shooters who demand consistent performance from their defensive handgun ammunition. Built around the Lehigh Defense Xtreme Defense solid copper bullet and nickel-plated brass casing, this load is optimized to deliver deep penetration and a large permanent wound cavity while maintaining reliable feeding and reduced fouling.

This 9mm Luger +P cartridge uses a 68-grain solid monolithic copper projectile driven to a muzzle velocity of 1800 fps, producing approximately 489 ft-lbs of energy. Radial flutes in the bullet nose channel hydraulic energy to create a wide, stable wound path even through common barriers, while flash-suppressed powder helps preserve sight picture in low-light conditions. Ideal for personal protection and training with carry guns rated for +P ammunition, it reflects Underwood Ammo’s focus on precision loading and consistent real-world performance.
