The Underwood Ammo 9mm Luger 115 Grain Xtreme Penetrator Solid Monolithic round is engineered for shooters who want consistent performance from a compact, lead-free defensive load. Built around Lehigh Defense’s Xtreme Penetrator copper bullet, this cartridge pairs precision CNC machining with Underwood’s carefully tuned powder charge for reliable function and repeatable accuracy.

This 9mm Luger load uses a 115 grain solid copper projectile that maintains its shape instead of expanding, driving deep while the fluted nose creates a large permanent wound channel through hydraulic pressure. Nickel-plated brass cases and boxer primers support smooth feeding, easy extraction, and straightforward reloading, while flash-suppressed powder helps preserve sight picture in low light. With standard-pressure operation and supersonic velocity, it is well suited for personal protection, everyday carry, and training, backed by Underwood’s reputation for consistent, high-performance ammunition.
