The Underwood Ammo 638 Xtreme Defense 380ACP 68gr Solid Monolithic 20 Per Box/10 Case is engineered as a high performance defensive load for compact .380 ACP pistols. Each round uses a Lehigh Defense Xtreme Defense solid copper projectile seated in a nickel-plated brass case, delivering supersonic velocity and consistent, controlled penetration with minimal recoil. The fluted monolithic bullet transfers energy through fluid displacement rather than traditional expansion, creating a large permanent wound cavity while remaining lead free and suppressor safe.

This .380 ACP load is well suited for personal protection and everyday carry, especially in small semi-automatic handguns where reliable feeding and clean-burning, flash-suppressed powder are important. Its optimized 68 grain bullet and 1300 fps muzzle velocity provide a balance of penetration and manageable recoil for defensive training and range use. Underwood Ammo is known for carefully tested, high performance ammunition built with quality components and attention to detail.
