Overview

Underwood Ammo's Xtreme Defense Platinum series in 9mm Luger features a 68-grain solid monolithic copper bullet. Designed for personal defense, this ammunition utilizes an optimized nose flute to create a permanent wound cavity (PWC) significantly larger than traditional hollow points. The unique design forces hydraulic energy inward, ensuring consistent performance and penetration—up to 18 inches—even when firing through barriers such as wallboard, sheet metal, or automotive glass. Each round is built with high-quality, nickel-plated brass casings, which offer enhanced corrosion resistance, smoother feeding, and easier cleanup for reloaders. The powder is flash-suppressed to preserve night vision during low-light use. Rated for supersonic velocities at 1700 fps with 436 ft-lbs of muzzle energy, this ammunition is new production, non-corrosive, and boxer-primed. Each box contains 20 rounds.
