If there was ever a high-velocity .45 Colt self-defense cartridge, then you’re looking right at it. At 1,410 fps, its muzzle velocity is high enough to transfer nearly *600* ft lbs of kinetic energy into its target at close range. Let’s see the 9mm Luger do that!

But this isn’t an overpressure load. Its amped up muzzle velocity is the product of its extremely light bullet: 135 grains, which it owes to its lack of dense lead. It’s the solid copper Xtreme Defender, and speed is only one of its many talents.

The Xtreme Defender bullet is one tough nut. High-velocity collision with a barrier barely robs it of any of its weight, which makes sure it keeps enough of its momentum to poke a very deep hole into the threat.

But deep penetration is only half of the Xtreme Defender’s terminal ballistics. The other piece is a mammoth wound cavity, which it excavates by engaging with soft tissue and torrenting it outward in four lateral directions.

The Xtreme Defender is Lehigh Defense’s doing. This ammo’s nickel-plated brass cases (which reduce friction and fight off corrosion), low-flash propellant (which conserves eyesight’s acclimation to darkness), and extreme reliability are all on Underwood.
