Underwood Ammo Xtreme Defense Platinum 9mm Luger +P 90gr Solid Monolithic - Box or Case

The Underwood Ammo Xtreme Defense Platinum in 9mm Luger +P is a premium personal-defense load built around a 90 gr solid monolithic projectile. The bullet's optimized nose flute, controlled total weight, and tuned velocity profile are engineered to drive penetration up to 18 inches while producing a clean, consistent permanent wound cavity. A solid copper body keeps the projectile stable through intermediate barriers like wallboard, sheet metal, and automotive glass, so the permanent wound channel is not lost when those materials are encountered.

This +P pressure load launches the 90-grain solid at 1475 fps, generating 435 ft lbs of muzzle energy. Casings are nickel-plated brass for smoother feeding, improved corrosion resistance, and reliable extraction in carry-grade defensive pistols and revolvers. The Platinum designation marks this as Underwood's premium tier of personal-defense ammunition.
