Our 40 Xtreme Defense Rounds are designed to deliver maximum stopping power for defensive situations. The rounds feature an advanced design which creates massive energy transfer and upon impact. Not only are the rounds accurate and reliable, but they are also engineered to penetrate barriers with minimal deformation and fragmentation, making them ideal for defensive use. 

For a more traditional hollow point, the 155gr or 180gr HPs will penetrate and expand immediately on impact, stopping the projectile from unnecessary overpenetration.
