Underwood Ammo Xtreme Penetrator .380 ACP +P 90gr Solid Monolithic - Box or Case

The Underwood Ammo Xtreme Penetrator is a serious .380 ACP +P personal defense load built around a Solid Monolithic projectile designed for deep, consistent penetration. Loaded to hot +P pressure levels, this round drives a 90 grain bullet out of the muzzle at 1200 fps, producing 288 ft lbs of muzzle energy that punches reliably through heavy clothing and intermediate barriers instead of fragmenting on impact.

Underwood loads premium components to exacting tolerances, and the Xtreme Penetrator line continues that tradition. The Nickel-Plated Brass casings feed smoothly, resist corrosion during long-term magazine storage, and provide dependable ignition across the full range of compact and subcompact .380 ACP carry pistols. Each box contains 20 rounds, and a full case supplies 200 rounds packaged as ten boxes for high-volume defensive training and stocking up.

Engineered primarily for personal defense, the solid monolithic construction of this projectile retains mass and drives deep toward vital structures rather than shedding weight on hard surfaces. Whether kept loaded for home defense or cycled through defensive drills, this .380 ACP +P load delivers the consistency experienced concealed-carry shooters expect from Underwood Ammo.
