The Lehigh Defense Xtreme Defense 45 ACP 190gr represents a significant advancement in self-defense ammunition technology. This fluid transfer monolithic bullet design delivers maximum stopping power through controlled energy transfer rather than traditional expansion. The solid copper construction ensures consistent performance across all shooting conditions.
What Makes This Different
Unlike conventional hollow point ammunition that relies on expansion for effectiveness, the Xtreme Defense utilizes precision-machined flutes that create fluid transfer channels. These channels generate temporary wound cavities through hydraulic shock while maintaining structural integrity. The monolithic copper construction eliminates the risk of jacket separation that can occur with traditional bonded bullets, ensuring the projectile maintains its intended weight and trajectory.
Key Features
- 190-grain solid copper monolithic construction for 100% weight retention
- Precision-machined fluid transfer flutes create maximum tissue disruption
- Feeds reliably in all 45 ACP firearms including 1911s and polymer frames
- Consistent 1.260-inch overall cartridge length meets SAAMI specifications
- Lead-free construction safe for indoor ranges and environmentally sensitive areas
- Nickel-plated brass cases resist corrosion and aid in extraction
- 50-round packaging provides sufficient quantity for carry rotation and practice
Field testing demonstrates the Xtreme Defense maintains terminal effectiveness through heavy clothing, drywall, and automotive glass without losing structural integrity. The controlled expansion design produces consistent penetration depths between 12-18 inches in ballistic gelatin, meeting FBI protocol standards. Law enforcement agencies report reliable feeding and ejection across diverse 45 ACP platforms, from compact carry guns to full-size duty weapons.
