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.
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.

MY NEW CCW AMMO
Posted by Ed on 16th Oct 2015
Underwood's loading using the 124 gr Speer Gold Dot is very impressive. It is accurate and powerful with velocities out of my full size Ruger SR9 coming in close to that of a 357 Sig. Recoil was only slightly more than the +p ammo I had previously used. No malfunctions of any kind. The brass is of high quality with the stamp "UNDRWD 9MM +P+". Unlike other manufacturer's CCW loads, Underwood's pricing is very reasonable for such a superior load.

This ammunition works well in my Smith &Wesson 915. And 5904. I replaced the recoil spring to 22 bl . No need to replace the mag spring, unless it makes you feel better. Bullet impact hit slightly lower, average 1 3/4 inch at 21 feet. This was expected.
Best carry ammo !

I use this ammo in my everyday carry. I trust it with my familys and my life. Shoots great and never a single issue though my glock 19 gen 4. I will continue to use this as long as it's available to buy.
.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.
Posted by Willy on 8th Jun 2015
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!
Posted by Daniel Stinebaugh on 29th May 2015
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!
Posted by George Brudnak on 6th May 2015
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.
