9mm Luger 90 Grain Xtreme Defender

0.55 LBS

Product Description

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 hollowpoint 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. 
*Falling within FBI guidelines 
This round offers:
  • A permanent wound cavity (PWC)that is 2 times greater than any expanding bullet
  • Reduced recoil.
  • CNC machined from solid copper to overcome barriers to penetration
  • 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
 Nickel plated casings with our new nickel plating process provides several key benefits, not limited to but including; improved feeding in all actions of firearms, enhanced corrosion resistance over traditional brass, improved cosmetics, and ease of cleanup during reloading.  Nickel plated casings will not tarnish like brass during storage or when in contact with foreign materials such as leather, moisture, and other metals.
Until the development of the Ducta-Bright 7a process, nickel plating casings often limited the number of reloads as compared to raw brass.  It was claimed that nickel plated brass casings “embrittled” the brass therefor making it less desirable for reloaders despite the ease of cleanup that nickel plating offers.  In addition, ammunition engineers raising concerns of using nickel plating in “very hot” +P or magnum loads found that traditional nickel plating often cracked deep-drawn cases, or worse, lead to a total failure. This new process eliminates any concern, to the shooter or reloader, of hazard or ability to re-use the brass.
As with all of Underwood Ammo’s rounds, we utilize flash suppressed powder so that your vision will not be compromised if it becomes necessary to use your firearm in low light.
While taking advantage of our state of the art testing equipment, this high performance ammunition is field tested using popular, real firearms that our 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, we stand by our product 100% and will make sure the customer is satisfied with every purchase.
This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.

    The best ammo I have ever used! I recommend it to everyone I know that carries a handgun!

  2. Hope I never find out 4 Star Review

    Posted by on 1st Dec 2016

    Seen videos on the Defender rounds and that was enough for me. Maybe someday I will waste a box on something. Till then, I'll be happy knowing what they are capable of.

  3. Best Defensive 9mm bullet (period!) 5 Star Review

    Posted by on 13th Oct 2016

    I can find no other bullet that meets so many standards for what a defensive bullet should be! If you do the research, you will find, this is THE bullet to have!

  4. Good test 5 Star Review

    Posted by on 23rd Sep 2016

    Testing was done on an out side range at 30 feet the performance was great, groups were small this will make a great personal protection round ,9mm 90 grain

  5. Xtreme Defense IS THE AMMO 5 Star Review

    Posted by on 5th Sep 2016

    From everything I've read, watched, and put thru my own 9mm, this ammo IS the ammo to carry! Underwood has a huge rep for putting out quality products, so I was super glad to see Underwood carrying this bullet. It is the ONLY bullet I carry for personal defense in all my 9mm (my 380 I travel with as well!). I've shot several hundred rounds of this, just to make sure, and I've not had one problem with it. GREAT stuff, GREAT job Underwood!

    1st. time today at indoor range. I'm impressed, clean good looking packaging, clean rounds, also they are clean shooting. good grouping. recoil is nice, the hole in target 20 ft. looked like the bullet face , a ''t'' neat. . 357 mag Penatrators to try next.

  7. Research Driven 5 Star Review

    Posted by on 21st Jun 2016

    After putting in several days of research, I came to the conclusion that this particular bullet displayed characteristics I was looking for, It will stop the threat with one round and, not pass through to injure an innocent.

  8. Excellent Performance 5 Star Review

    Posted by on 20th Jun 2016

    Ran 40 rounds through my Springfield XDm 3.8. Flawless functionality and good accuracy through my pistol. I didn't expect how much lower the recoil and muzzle flash was compared to other defensive ammo at the same chamber pressures.

    With the tests I have seen and the performance I have felt, this is my new defensive / carry ammo for my Springfield.

  9. Perfect Ammunition 5 Star Review

    Posted by on 31st May 2016

    Ran 40rds through my Wilson XTAC compact with 2 different magazines..... No failures to feed or eject. Excellent accuracy at 30'. Highly recommended in a 9 Millie Compact.

  10. High performance 5 Star Review

    Posted by on 28th Apr 2016

    These Underwood xstream Defenders have the performance you want and the quality you need. Function is flawless.
