Underwood Xtreme Defender .40 S&W Ammo – 140 Grain Solid Copper Fluted Personal Defense Rounds (20 Round Box)

Underwood Xtreme Defender .40 S&W 140 Grain ammunition is a high-performance defensive load built for shooters who demand maximum stopping potential, reliable feeding, and modern terminal effectiveness. Known for producing some of the most powerful handgun ammunition available, Underwood designed the Xtreme Defender line to deliver consistent real-world performance for personal protection and duty use.

This load features a 140 grain solid copper Xtreme Defender projectile with a patented fluted design that creates devastating energy transfer and consistent wound channels without relying on traditional hollow point expansion. This makes it an excellent option for dependable performance through heavy clothing and common barriers, while still maintaining effective penetration.

Optimized for .40 S&W defensive pistols, the lightweight 140 grain bullet provides fast, controllable recoil and flat-shooting performance, making it a strong choice for concealed carry, home defense, and serious defensive readiness. Packaged in a convenient 20-round box, it’s ideal for carry rotation and personal protection preparation.
