Design Philosophy

The Lehigh Defense Xtreme Defender bullet is engineered to provide consistent, controlled expansion without relying on hollow-point technology. This design offers several practical advantages: it functions reliably through intermediate barriers, maintains structural integrity, and delivers energy transfer through its unique construction.

The 100-grain projectile at 1200 fps represents a balanced load—offering adequate velocity for the .38 Special platform while remaining controllable in lighter-framed revolvers. Nickel-plated brass cases provide corrosion resistance and reliable feeding characteristics.

Suitable For

This ammunition works well for personal defense, duty use, and practice with .38 Special revolvers. The moderate recoil makes it accessible to shooters of varying experience levels while maintaining defensive capability.
