Overview

Underwood Ammo’s 9mm Luger 115gr Xtreme Penetrator ammunition is a lead-free, solid copper round engineered for self-defense applications. Designed with a unique nose profile, the bullet is optimized to facilitate reliable magazine feeding while creating high pressure spikes and a large permanent wound column for superior terminal performance. This solid copper design is capable of punching through entry barriers without deformation or deflection and offers deep, straight penetration. Each cartridge features a nickel-plated brass casing, which provides enhanced corrosion resistance, smoother feeding, and easier cleanup compared to traditional brass. The ammunition is loaded with flash-suppressed powder to preserve night vision during low-light use and is safe for use in suppressed firearms. The round is non-corrosive, boxer-primed, and reloadable, with a muzzle velocity of 1,150 fps and a muzzle energy of 338 ft-lbs.
