Underwood 45acp+p 135gr - Xtreme Defender 20rd 10bx/cs

Underwood 45acp+p 135gr Xtreme Defender ammunition delivers purpose-built self-defense performance for duty and civilian carry applications where stopping power and reliability are non-negotiable. Engineered by Underwood Ammo—a trusted name in premium defensive ammunition—this load represents the evolution of .45 ACP ballistics, combining modern projectile technology with +P pressure ratings to maximize terminal effectiveness while maintaining full controllability in service-grade platforms. Law enforcement and armed professionals choose this round when standard loads fall short of mission requirements.

The 135-grain Xtreme Defender projectile is engineered for rapid expansion and deep penetration—a critical design balance in intermediate barriers and various clothing conditions. The +P pressure rating increases velocity and kinetic energy without requiring firearm modifications, though use should be confirmed with your specific platform manufacturer. Each factory-sealed box contains 20 rounds of consistently loaded ammunition, with 10 boxes per case ensuring adequate supply for serious defensive training or duty inventory. Underwood's quality control and brass casings provide the reliability demanded in life-or-death scenarios.

This load is ideal for compact and full-size .45 ACP platforms—M1911s, Glocks, and modern service pistols—that have been proofed for +P ammunition. Before use, verify your firearm's specifications and manufacturer guidance; some compact models or vintage platforms may have limitations. The 20-round box format is favored by duty shooters and practitioners who rotate defensive loads regularly, ensuring ammunition freshness and reliability during critical moments. Store in cool, dry conditions away from moisture to maintain primer integrity and case condition.
