Underwood Xtreme Defender .380 ACP 68gr Solid

Underwood Xtreme Defender: Purpose-Built Self-Defense Performance

The Underwood Xtreme Defender represents a thoughtful approach to personal protection ammunition. Built on proven engineering principles, this .380 ACP round combines velocity, bullet construction, and terminal performance in a package designed for serious defensive use.

Penetration and Wound Cavity

The Xtreme Defender achieves penetration depths up to 18 inches while creating a permanent wound cavity significantly larger than conventional expanding hollow points. The solid copper construction ensures consistent performance regardless of intermediate barriers—wallboard, sheet metal, or automotive glass will not degrade the round's effectiveness.

Case Construction

Nickel-plated brass casings offer distinct advantages over traditional brass. The nickel plating improves feeding reliability across all firearm actions, provides superior corrosion resistance, and resists tarnishing during storage or when exposed to moisture and other environmental factors. Cleanup during reloading is simplified.

Performance Characteristics

This is new production, non-corrosive ammunition rated safe for use in suppressors. The round travels at supersonic velocity and is suitable for both hunting and self-defense applications. The solid copper construction eliminates lead concerns while maintaining the penetration and wound-channel characteristics essential for reliable stopping power.
