Experience superior personal defense with the Underwood Ammo 816 9mm Luger +P Xtreme Defender rounds. Designed for maximum penetration and expansion, these rounds feature an optimized nose flute, total weight, and velocity that deliver up to 18 inches of penetration depth with a permanent wound cavity (PWC). Unlike conventional hollow points, the Xtreme Defender's cavity exceeds 100% larger than typical expanding bullets, providing superior tissue damage potential even after passing through barriers such as drywall, sheet metal, or automotive glass. The solid copper construction ensures consistent performance without deformation, maintaining a stable wound channel regardless of obstacles encountered in real-world scenarios. These rounds are ideal for personal defense, combining deep penetration with significant wound volume for effective stopping power.

The nickel-plated brass casings enhance feeding reliability across all firearm actions, resist corrosion, and maintain a clean appearance during multiple reloads. The nickel finish prevents tarnishing from moisture, leather, or other environmental factors, ensuring the rounds are ready when needed. With a muzzle energy of 435 ft-lbs and a velocity of 1475 fps, the 90-grain monolithic bullets provide a balance of power and accuracy, making them suitable for a variety of self-defense situations.
