Built with all new components, the TCX9 is a 115 grain, 9mm Luger+P Solid Copper Defensive round.

The TCX9 offers a muzzle velocity of 1,275 feet per second and 415 ft/lbs of muzzle energy, as tested in a standard Glock 17, 4.49 inch barrel.

ALL of our auto pistol brass is case cannelured in house to prevent bullet setback.

Why is this important? Bullet setback can occur with a pistol malfunction, or from chambering the same round over and over again. This can lead to possible CATASTROPHIC failure. The cannelure line puts a “crimp line” where the base of the bullet ends up. So if bullet setback were to occur, the bullet will NOT push passed the cannelure line. It’s a time consuming process, therefore, VERY few ammunition companies cannelure their brass. Here at Defiant Munitions we want our customers to have nothing but the BEST, most reliable round possible. Extra steps will always be taken here to ensure the safety and quality of our products.

Don't be fooled by the price.  Most quality defensive ammo is packaged 20 to a box.  The Defiant Munitions TCX9 is packaged 50 rounds per box, because you should have the same ammo in your spare magazine as you do in your primary.

We build these to our exacting standards to ensure you have only the most consistent and reliable defensive ammo available.

9mm Luger 115 gr +p TCX

Don't settle for less that the best for your own safety. Defiant is my preferred for both concealed and home defense. Top quality product with service to match. In uncertain times, this is one less uncertainty. Highest recommendation!

9mm TCX

I was recommended DM by a friend a long time ago, before the ammo started being actually made. Based completely on the reputation of the person running things. And after the wait I have to say it was totally worth it. TCX is hands down all I will carry in my guns and it's all I recommend to my family and friends. Will be stocking up on this as it becomes available!

DM 9mm 115 gr +P TCX

The velocity and expansion of this round allows me to carry my P365 with confidence. I load my deep cover weapons with nothing else.


I love these TCX rounds, and you won't find a better company to work with.

9mm Luger 115 gr +P TCX (Total Copper X-panding) Solid Copper Defensive Ammunition

I find that these rounds are are consistent, and very accurate, and with the level of detail that went in manufacturing these rounds to prevent bullet setback is just amazing.

My new carry ammo

I was a big fan of the corbon dpx. Now that Defiant is up and running I am making the switch. I didnt notice this being any hotter than other carry ammo. It feed without issues in my Glock 19. I will be buying more. I think total copper is the best.

Amazing Performance

The new 115 TCX is amazingly consistent. QC on this ammo is second to none. Chrono’d out of my Langdon 92 at an AVG of 1269 FPS with a standard deviation of 5 FPS! Profile and overall length ensure reliable feeding across multiple types of pistols. The only 9mm defensive ammo I will carry from here on out.

9mm rounds review

Canik USA told me they couldn't recommend DM ammunition enough as the best ammo to use in my TP9SFX. Just received 2 boxes and they are made above the standards of some of the best ammo on the market. Cant go wrong, outstanding quality. Highly recommended.
