While taking advantage of state of the art testing equipment, this high performance ammunition by Underwood is field tested using popular, real firearms that customers are most likely to own out in the real world with all the elements you would experience. If for some reason Underwood Ammunition fails to meet performance expectations, Underwood stands by their product 100% and will make sure the customer is satisfied with every purchase. This 9mm luger ammunition is new production, non-corrosive, in boxer primed, reloadable nickel plated brass cases.
The Xtreme Defender is based on the popular Xtreme Penetrator product line. The XD ammunition has an optimized nose flute, total weight, and velocity to achieve a penetration depth up to 18 inches with a permanent wound cavity (PWC) that is just simply enormous; no other expanding hollow point comes close to achieving anywhere near this diameter and volume. Not only is the PWC over 100% larger than any other expanding bullet, expansion is achieved despite being shot through barriers. The solid copper body ensures that wallboard, sheet metal, and automotive glass will have no effect on the Permanent Wound Channel. All of Underwood 9mm luger Ammo rounds utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
- Reduced recoil
- Radial flutes that force the hydraulic energy inward to build pressure
- Minimal surface area to increase the force at the point of contact and sharp cutting edges that defeat barriers
