Underwood ammunition combines proven power and precision with Lehigh Defense's masterfully engineered Xtreme Penetrator bullet design. This round delivers the performance demanded by serious shooters who require reliable penetration and consistent function.
The Xtreme Penetrator design represents a thoughtful approach to ammunition engineering. The solid copper construction eliminates lead concerns while the blunt nose design provides the deep, straight penetration serious shooters demand. Nickel-plated casings resist tarnishing during storage and maintain their appearance when exposed to moisture, leather, or other metals—a practical advantage for those who reload or store ammunition long-term.
Whether you're training, competing, or preparing for self-defense, Underwood's 9mm Luger delivers the reliability and performance you can depend on.
