The Underwood Ammo 639 Xtreme Defense 380 ACP +P 68gr Solid Monolithic round is engineered for shooters who demand consistent performance from a compact defensive cartridge. Built around Underwood’s Xtreme Defender Fluid Transfer Monolithic projectile, this load combines a solid copper bullet with carefully tuned velocity to deliver deep, controlled penetration and a substantial permanent wound cavity while remaining lead free.

This 380 ACP +P ammunition is ideal for personal protection, everyday carry, and training with your carry gun when you want the same recoil impulse and point of impact as your defensive load. Nickel-plated brass cases enhance feeding and resist corrosion, while flash suppressed powder helps preserve sight picture in low light environments. Each box contains 20 new-production, non-corrosive, boxer-primed rounds, reflecting Underwood Ammo’s focus on innovation and reliable performance.
