Underwood Xtreme Defender 32 ACP+P Ammunition
The Xtreme Defender represents a significant advancement in defensive ammunition design. Built on proven Xtreme Penetrator technology, this load delivers performance characteristics that set it apart from conventional expanding hollow points.
Ballistic Performance
- Caliber: 32 ACP+P
- Bullet Weight: 55 grains
- Muzzle Velocity: 1050 FPS
- Bullet Construction: Solid monolithic copper

Design Features
The solid copper construction ensures consistent performance regardless of barriers. The optimized nose flute geometry is engineered to achieve penetration depths up to 18 inches while creating a permanent wound cavity significantly larger than conventional expanding bullets—over 100% larger in diameter and volume.
Unlike traditional hollow points that lose effectiveness when passing through intermediate barriers, the Xtreme Defender maintains its wound-creating capability after penetrating wallboard, sheet metal, and automotive glass.
Case Quality
Nickel-plated brass casings provide multiple advantages: improved feeding reliability across all firearm actions, superior corrosion resistance compared to traditional brass, enhanced cosmetics, and easier cleanup during reloading. The nickel plating prevents tarnishing during storage and resists discoloration from contact with leather, moisture, and other metals.
20 rounds per box, 10 boxes per case.
