October 7, 2021Unreliable for defense
Purchased earlier this week thinking this was ammo I wanted. At the range I shot one box (20 rounds). Feeding these rounds into my Walther PPS became an issue. The shape of the round appears to be the problem for me. One jam occurred while firing the third round, and the second jam occurred while loading the firearm. This is suppose to be Xtreme Defender Ammo, but… read more I was disappointed at these jams. Perhaps the ammo is good for plinking, but I do not believe I could rely on it in a firefight.

Runs really well, even in my little Kimber Micro 9 that's kinda finicky about ammo. Very soft shooting, but still obviously less drop at 25 yards than most loads, including the Federal HSTs I previously used as a carry load, very consistent groups compared to other higher velocity 9mm I've tried. Fast shipping and great prices (for the times) as usual from Lucky Gunner.

August 6, 2021Great product
This is a great product. They cycle perfect in my Shield Compact w/laser and the recoil isn’t much. If I wanted to stop somebody I choose these or 150 grain HST …I value consistency over ALL.

Really like the design of the ammo. Like the weight of the grain, and seems to get good reviews from others who have tested It.

May 26, 2021Great ammo
Great ammo!! Shot a couple boxes out of my m&p to test reliability, no issues @ all. Recoil was very much manageable. My gun feels so light filled to the brim, since its only 90g. I will continue to purchase this ammo. .

9mm - 90 Grain Xtreme Defender - Underwood - 20 Rounds Questions and Answers
My sar9mm has a heavy recoil spring can use this ammo since is a 90 grain bullet
Thanks for reaching out Carlos! While this cartridge has indeed got a lightweight bullet, it still meets SAAMI specs thanks to its faster than average 1,400 fps muzzle velocity. While I cannot guarantee reliable performance in a handgun I have not tested
I have a ruger P89 is this bullet type safe for my gun.
Thanks for reaching out Sean! This ammo is designed to function safely and reliably in any 9mm firearm.
I have been told that it is dangerous to fire +P ammo in a handgun. I saw an answered question that stated this was not +P ammo, but it says +P on the box. Is it safe to use in my M&P 9mm EZ? The ammo in question is 9mm Luger +P 90gr Underwood ammo.
Thanks for reaching out Herbert! This is not +P ammo. Its muzzle velocity is certainly higher than the typical 9mm round's, but that's the product of its lightweight 90 grain bullet, not a higher power propellant charge. A 90 grain bullet loaded to a muzz
Louisiana requires hollow point in postal’s. Does this qualify
Thanks for reaching out Jonnie! I'm not remotely qualified to interpret state law, so please don't take anything I say as legal advice. That said, this isn't hollow point ammunition, so I'm uncertain whether it's barred for CCW under your state law.
If I purchase today, will you ship or tell me the shipment is delayed or you ran out of ammo. If I pay and you can’t ship then how do I get an immediate refund?
No sir, we're proud not to do business that way. You can see exactly how many boxes of this ammo we currently have in stock next to the "Add To Cart" button. If you can order it from us, then you can count on us shipping it to you.
Is this amo good for Gluck 48
Yes sir, this ammo is designed to function correctly in any 9mm firearm. A G48 should run this ammo great!
Is this ammo compatible with a Smith & Wesson M&P 9 firearm?
Absolutely sir! This ammo should function correctly in any firearm chambered for 9mm, your M&P included.
Will my order come in for sure and do y'all age check
Thanks for reaching out Kentrall! We do request to check ID when our customer lives in a state where the law requires us to verify that they are over 21 years old. You can learn more about our shipping service and check your state's requirements here: luc
The question, Do you have or are you planning on showing a video test regarding penetration of the ammo?
Thanks for reaching out Angel! I'm uncertain when we'll publish a gel test for this ammo, but this fellow on YouTube has already done one if you'd like to have a watch:<br> <br> https://www.youtube.com/watch?v=Qx-qn5BnSD0&ab_channel=AP2020Outdoors
I'm impressed with this ammunition. Is the Xtreme Defender safe to run through the Taurus G2C?
Thanks for reaching out John! This ammo should treat any semi-automatic pistol properly, your G2c included. Despite its unconventional bullet it's still loaded to SAAMI specs, so it's not going to generate chamber pressure that could damage your handgun.
Will this ammo work for PX 4 storm type F 9mm Barrett’s?
Yes ma'am, this ammo is a good choice for self-defense with a PX4 Storm!
Do yall have 9mm ammo rite now
Yes sir, we have got a few options in stock: luckygunner.com/handgun/9mm-ammo
is It per round or per box ??
Hi Alex! Our price is for a box of 20 rounds.
What is the difference between 9mm and 9mm Luger. Are the shell's interchangeable. Thank you !
Thanks for reaching out Pete! 9mm and 9mm Luger are the exact same cartridge. It is also known as 9x19, 9x19mm Parabellum, and 9mm Parabellum.
will my Sig Saur P320 RX be able to shoot +P ammo
Yes sir, your handgun is designed to safely fire 9mm +P.
Hi, Would this be good ammo for a Staccato C2?
Yes, Staccato's pistols are designed to safely fire +P ammunition. This ammo will wear out your semi-auto's moving parts faster, although that's really not of concern for ammo you'd only employ for self-defense.
Are you able to ship to Anchorage AK?
Sorry sir, we can't ship outside of the continental U.S.
I have a Spring field Armory XDM 9MM. Would it be safe to shoot 9MM LUGER + P 124 Grain jacketed hollowpoint in this weapon? I was told by my son in law that i could not???? Thank you
Hello Floyd! Just to be sure, this isn't hollow point ammunition. The bullet is made of solid copper and doesn't expand inside soft tissue. It's shaped like a drill bit and uses fluid physics to essentially "stir" a giant wound cavity into its target.
Hi, Would this be good ammo for a Glock 43?
Absolutely, this ammo is a good choice for self-defense with a G43.
I have a m&p shield 2.0 is this a good ammo for it and also for a carry conceal?
Absolutely Kurt, this is extremely potent self-defense ammo and it should function very well in your handgun.
How much concern should I have for over-penetration -vs- a standard hollow point?
Hi Sean! Interestingly enough, this ammo actually reduces the chance of overpenetration. A traditional hollow point bullet may fail to expand, which in turn will increase its likelihood of overpenetrating. This ammo's bullet doesn't rely on expansion to t
Do you think this is good ammo gor my wife’s S&W MP 9MM?
Without question! This ammo is high quality, reliable, and low recoil, and its bullet devastates as it penetrates up to 18" in soft tissue while excavating a tremendous wound channel. I'm a huge fan of monolithic bullets because they cause so little fouli
Is this round rated as standard pressure, +p, or +p+ ?
Hello there! This is standard pressure 9mm ammo, not +P or +P+.
