Most Helpful Positive Review HANDS DOWN THE BEST DEFENSIVE CARRY AMMO
I've switched all of my carry ammo to the +P Underwood Extreme Defender! I have the 9mm and .380 in the 90gr +P variant and for +P rounds they sure don't kick like GD & HST yet leave a Pic twice the size of either! As if that weren't enough they're barrier blind and STILL FUNCTION as intended after passing through clothing, wallboard, auto glass, etc. Best innovation in bullets since the hollow points!

Good All Around

by USA, Verified Owner from TX, United States Written on May 21, 2025
Possibly the perfect 9mm round. Light, slick, fast and will penetrate a Bear Skull if necessary but will create enough disruption to use as an everyday self defense round.

Like no other defense ammo available, these rounds work!

by StraightShooter, Verified Owner from NC, United States Written on October 26, 2024
Tested several barriers, nothing stops, or deforms the projectile until it enters it's designated medium! There ARE my EDC +1 and dedicated home defense loads. I prefer the +P varieties of BOTH the 9mm AND .380! I'd love the see some 22wmr varieties of these projectiles in a 40 to 50 grn
Pros:
  • unwavering reliability and consistent performance
Cons:
  • ppr, but OUTSTANDING PWC results
Best Used for:
  • for barrier blind smmo, in a +P load, you're not going to find BETTER!
Would recommend: Yes

Good ammo, lightweight!

Good ammunition, lightweight, shoots great and the price is right. It feeds well too. Super fast so i wasn't expecting the boom at first. I need some more.

Great ammo

by Andrew, Verified Owner from TX, United States Written on March 16, 2024
The ammo feeds well in my Sigs and Taurus. I haven't had any problems with it yet. I'd recommend this over standard hollow points.

Good Defensive Ammo

by CNS, Verified Owner from TN, United States Written on January 12, 2024
This seems like good defensive ammo. I am confident that it will always feed well in my Glocks and SW M&P. About the same price as other reputable defensive ammo. Hope I never have to use it for the purpose for which it was designed.
Pros:
  • well made
  • Well packaged
  • Light recoil
  • evidence of good ballistic performance
Cons:
  • A little hard to find
Best Used for:
  • Self defense
Would recommend: Yes
