Underwood Ammo’s bonded rounds are unrivaled in power and precision. We utilize Speer bonded bullets which employ an exclusive Uni-Cor process where they bond the jacket to the core one molecule at a time. This essentially eliminates core-jacket separation, maximizes weight retention, and allows for unparalleled penetration and controlled yet fatal expansion.
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.

.357 Sig by another name
Posted by Leo on 25th Jul 2015
For a self defense caliber I had always thought that the .357Sig was the best round, especially with the results that Law Enforcement Agencies were getting with the Speer Gold Dot 125gr round.
That is, until I came across this round, it allows me to convert my P320 Carry back to 9mm, have the essentially the same effect as .357Sig in terms of penetration and velocity.
The extra benefit in this is that I can carry two more rounds in my magazine than I would be able to have with a .357Sig.
The other clear benefit is the price! At a much lower price than Speer's 9mm 124gr and .357Sig 125gr Gold Dots you get better performance and more bang for your buck.
Underwood Ammo has excellent products and I'll buy from here again.

My new carry ammo. The best penetration and expanding 9mm I have ever shot. Stout recoil compared to similar ammo but nothing unmanageable. My G19 likes it and my G17 loves it!

Again, underwood has a home run with this load! Out of a G17 no issues at all and averaged 1324 fps over a pro chrony! Underwood is what I carry in all my weapons and has never let me down, would trust my life to this ammo!
Excellent Short barrel ammo.

Fired out of a Kahr PM9 into gallon water jugs, this 124 grain +p+ round expanded more than a standard pressure Gold Dot from a Glock 19. Recoil in the little pistol is much sharper, but easily controlled. I highly recommend this round for Short barreled self defense pistols. I would not use a lot of them for practice though, because of possible wear and tear, and be sure your pistol can at least handle +p cartridges before trying these. Accuracy was excellent.
Super Hot Ammo!

Man these really rock and roll! Consistent speeds (always a touch over what's displayed but very tight tolerances) and hard hitting, no problems in feeding or cycling, however in my HK usp 9 it will occasionally pop the magazine loose but that's not the ammo's fault just an example of how hot this stuff really is!

Excellent ammo in every way,now just use nickel plated cases and it's the best,I prefer nickel,smoother feeding,best for long term carry,hash conditions,ie salt water,
Hot, accurate round
Posted by Paul S on 27th Apr 2015
Very well made rounds. Accuracy was very good, functioned perfectly. Hot for a 9mm. Will be stocking these up.
The Best ammo you can buy!
Posted by Al on 6th Apr 2015
I usually shoot Winchester Ranger +p+ 127gn ammo, but decided after using your 125gn Speer GDHP 357 Sig ammo to try your +p+ 9mm 124gn GDHP ammo. I'm so impressed that I've converted over to your ammo on my Sphinx SDP. This stuff is hot, and approaching standard 357 Sig velocities. Functioned perfectly and was very consistent. Accuracy is never in doubt with the Sphinx, and your ammo didn't disappoint. Thank you for an outstanding product that is reasonably priced.
Effective and manageable
Posted by Unknown on 5th Apr 2015
Shot out of ether of my 9mm handguns, P226 or FNS-9, recoil was very manageable and only barely noticeable difference from underwood's +P offering with the same bullet (As far as recoil goes). The effect on targets however is much more noticable. Exellent performance all around.
Wow I love these..
Posted by Josh W on 24th Mar 2015
A Speer GD loaded coming out of a 9mm with true asswhoopin force. Shot these from Glock 19, there was a noticeable difference in pressure but the recoil is still very 9mm user friendly. So one of the best hollow point designs for self defense with unparalleled power and an unbeatable price point. If your firearm can handle these, then these are a must have for the ballistic enthusiast.
