Product Description
Underwood Ammo Xtreme Defender Platinum Edition in .380 ACP is built around a solid monolithic copper projectile engineered for consistent, barrier-blind performance. The optimized fluted nose design transfers energy through fluid displacement to create an exceptionally large permanent wound cavity while maintaining dependable penetration (up to 18 inches within FBI guidelines). This non-expanding, lead-free bullet design helps reduce concerns associated with hollow point expansion failures through common barriers such as wallboard, sheet metal, and automotive glass. Nickel-plated brass cases are used to enhance feeding, improve corrosion resistance, and keep ammunition looking cleaner in storage, making this a strong choice for both personal protection and hunting applications.
