The Lehigh Xtreme Defense .40 S&W 115-grain round stands out because it doesn't rely on mechanical expansion like traditional hollow points. Instead, it uses Fluid Transfer Monolithic technology, which channels hydraulic energy through grooved flutes to create tissue damage that extends far beyond the bullet's diameter. The result is a permanent wound cavity two to four times larger than flat or round nose bullets, with penetration designed around 18 inches.
You're getting a solid copper bullet that maintains its integrity through impact, so it won't deform or lose trajectory when passing through barriers like drywall, heavy clothing, or auto glass. This barrier-blind capability means consistent performance regardless of what the bullet encounters, without the risk of over-penetration that can happen when hollow points plug up and revert to round nose behavior.
This ammunition delivers 1400 feet per second muzzle velocity and 500 foot-pounds of energy from a 5-inch barrel. The brass-cased rounds are boxer-primed for reload potential. Whether you're loading for self-defense or training, you get brass casings that maintain consistent quality.
People who've run Lehigh Xtreme Defense in various platforms report reliable feeding and consistent point-of-impact, with testing showing the round maintains performance even after passing through multiple barrier types. The monolithic copper construction makes these rounds environmentally friendly while delivering impressive stopping characteristics.
Rather than expanding mechanically, the Xtreme Defense uses grooved flutes that redirect hydraulic energy to create permanent wound cavities two to four times larger than conventional bullets. The solid copper construction doesn't deform on impact, maintaining its integrity even when passing through barriers like drywall or clothing.
Yes. Testing shows these rounds feed reliably across common pistol platforms including Glocks, Walthers, and other modern designs. The unusual nose geometry doesn't prevent reliable feeding from standard magazines, and point-of-impact remains consistent with your gun's zero.
Yes. These rounds use boxer-primed brass cases that can be reloaded. The solid copper projectile design makes reloading straightforward without the complications of hollow point press-seating.
Lehigh designs the Xtreme Defense for approximately 18 inches of penetration in testing media, which falls within the widely accepted range for self-defense ammunition. The round maintains this penetration depth consistently even after passing through barriers, unlike traditional hollow points that can over-penetrate when plugged or under-penetrate when deflected.
