Underwood Ammo UA 639 380 ACP+P Xtreme Defender 68-Grain Monolithic Centerfire Handgun Rounds

The Underwood Ammo UA 639 Xtreme Defender 380 ACP+P offers premium personal defense ammunition designed for maximum penetration and wound cavity size. Featuring a solid monolithic copper bullet weighing 68 grains, this round is engineered to penetrate up to 18 inches through barriers such as sheet metal, wallboard, and automotive glass, producing a permanent wound cavity (PWC) over 100% larger than comparable expanding hollow points. The optimized nose flute, combined with a total weight and velocity calibrated for high performance, ensures reliable barrier penetration and effective energy transfer, making it ideal for self-defense scenarios. This ammunition maintains its effectiveness even when shot through barriers, providing consistent expansion and wound channel formation in various conditions. The casing is made from nickel-plated brass, which enhances feeding reliability across all firearm actions, improves corrosion resistance, and maintains a clean appearance during reloading. Nickel plating also prevents tarnishing over time, ensuring the rounds stay in optimal condition for storage and use. Rated for +P pressure, these rounds deliver a muzzle energy of 296 foot-pounds at a velocity of 1,400 feet per second, combining power and velocity for effective personal protection. Packaged in boxes of 20 rounds with 10 boxes per case, the Underwood Ammo UA 639 offers a reliable and high-performance solution for handgun users seeking maximum barrier penetration and wound cavity size in a compact 380 ACP platform.
