Underwood Ammo 9mm 90gr Xtreme Defender - 20 Rounds Per Box

The Underwood Ammo 875 9mm 90gr delivers exceptional terminal performance through its innovative solid copper construction and fluted design. This premium defensive ammunition achieves maximum energy transfer while maintaining consistent accuracy across various pistol platforms.

What Makes This Different

Unlike traditional hollow point designs, the Xtreme Defender features a solid copper projectile with precision-machined flutes that create massive wound channels without relying on expansion. The 90-grain bullet weight provides reduced recoil while maintaining penetration standards that exceed FBI protocols. Testing demonstrates consistent 12-18 inches of penetration in ballistic gelatin with permanent wound cavities measuring 3-4 inches in diameter.

Key Features

• 90-grain solid copper Xtreme Defender bullet for maximum energy transfer

Field testing shows exceptional performance in both compact carry pistols and full-size duty weapons. The reduced recoil characteristics allow for faster follow-up shots while maintaining fight-stopping effectiveness. Law enforcement agencies report reliable function in Glock, Sig Sauer, Smith & Wesson, and other major pistol platforms. The nickel-plated cases cycle smoothly through semi-automatic actions and resist corrosion during extended storage.
