Underwood Ammo Xtreme Defender Features The Underwood Ammo Xtreme Defender is built on the design principles of the Xtreme Penetrator line optimizing nose flute geometry bullet weight and velocity to achieve deep reliable penetration. The solid monolithic copper bullet is engineered to create a permanent wound cavity over 100 percent larger in volume than typical expanding hollow point ammunition. Because the projectile is solid copper rather than a jacketed design it resists deforming or clogging when it has to pass through intermediate barriers such as automotive glass or wallboard before reaching its target. This makes it a dependable choice for shooters who prioritize terminal performance in a compact .32 ACP self-defense round. Each round is loaded into a nickel plated brass casing a finish that improves feeding reliability across different pistol actions while resisting corrosion better than traditional brass during storage. The nickel plating also simplifies cleanup for reloaders and helps the cases resist tarnishing from moisture or contact with leather holsters. At 950 feet per second and 110 foot pounds of muzzle energy the load is rated subsonic and is safe to run through a suppressor for reduced report. Packaged 20 rounds to the box the Xtreme Defender is available for sale at GrabAGun for shooters who carry a .32 ACP pistol for personal protection.
