Underwood 380 ACP Ammunition 68 Grain Xtreme Defender - 639
Underwood 380 ACP +P Xtreme Defender ammunition is engineered with the advanced EXD (Xtreme Defender) bullet design, a solid copper projectile optimized for self-defense. Unlike traditional hollow points, the EXD utilizes precision-cut flutes to redirect energy on impact, producing large wound channels without relying on expansion. This results in consistent terminal performance, reliable penetration, and dependable effectiveness even when encountering common barriers. With a lightweight 68-grain bullet moving at 1,400 fps, this load delivers high energy with manageable recoil, making it one of the most innovative defensive options available in .380 ACP +P.

- High Velocity & Energy: 1,400 fps muzzle velocity and 296 ft-lbs of muzzle energy.
- EXD Bullet Design: Fluted solid copper bullet engineered to transfer energy efficiently and create significant wound cavities.
