The Underwood Ammo 817 Xtreme Defense 9mm Luger +P+ 90gr Solid Monolithic cartridge is engineered for shooters who demand consistent performance from a compact defensive handgun. This load pairs a solid copper Xtreme Defense bullet with nickel-plated brass casings to deliver reliable feeding, impressive velocity, and a permanent wound cavity far larger than traditional expanding hollow points, even after passing through common barriers.

Designed specifically for personal protection and everyday carry, this 9mm Luger +P+ round offers reduced felt recoil, suppressor-safe operation, and flash-suppressed powder to help preserve sight picture in low light. Its radial flutes redirect hydraulic energy to maximize penetration and tissue displacement, making it well suited for defensive training and serious self-protection while reflecting Underwood Ammo’s focus on innovation and consistent quality.
