Compared To Other Top Self-Defense Rounds

Our projectiles function differently than any other self-defense round on the market. We designed the Civil Defense line to eliminate threats with one round. We did this by creating the maximum amount of damage and tissue disruption possible. They do well against barriers, but when the large cavity fills with fluid, the hydraulic pressure builds until the side walls of the projectile explode. With that explosion comes rifle-sized temporary cavities and hydrostatic shock, therefore increasing stopping power by tenfold. Following the explosion, the bullet fragments into a starburst-shaped pattern creating multiple wound channels. This process also benefits in many other areas across the spectrum of things considered when talking about self-defense. Such as reduced over-penetration and lessening the risk of unintended casualties. Having a lighter projectile also leads to less muzzle flips for faster follow-up shots. All of our rounds are also lead-free and California-compliant.

I’m stuck for words…. Unbelievable is an understatement. Less recoil out of Glock Gen 5 and the speed is noticable, especially at 25m. Of course I brought multiple milk jugs filled with Kool aid. Standard hollow points they shot put hole in and larger hole out. Liberty Civil Defense blew the jugs like a grenade!!! Needless to say they are all believers now!!! Expect many orders to GA.

Thanks Jason,

We appreciate it…….our projectiles rupture in the fluids (soft tissue).

Thanks for your support…..

Safe for a Sig 320?

They are made for one another.

These are brand new casings, Liberty does NOT do reloads.

Awesome Product

These rounds are a must have for your .40 cal. Especially for stopping power and less risk of collateral damage to unintended targets.


Response from Liberty Ammunition

Thank you, sir.

We believe we make the best self-defense ammo available.

We have more stopping power and all the energy is dumped into the threat.

What’s bullet weight diff between +p and ultra light +p?

Not grains the grains same.


Response from Liberty Ammunition

Total grain weight is 92gr for Ultra Light vs 120gr for Civil Defense (two random bullets pulled from boxes and weighed).

As a comparison, the new Federal self-defense round (“Punch”) is 190 grains.

Thats more than 2x the weight of Ultra-Light and 158% the weight of Civil Defense.

Are they safe with the SAR9 CX pistol?


Response from Liberty Ammunition

Larry, our ammo is designed with SAAMI standards.

If the SAR is designed to these standards as well, then you should be fine.

Great performance even in subcompact 9 mm pistols.

Incredible penetration, low recoil, fun to shoot and 100% reliable what’s not to love!


Response from Liberty Ammunition

Thanks Stu,

The penetration is fabulous and it’s even better when the projectile ruptures and stops the threat.

Our 380 Civil Defense Rounds Changed The Pocket Pistol Game. For A Long Time, Everyone Criticized The 380 ACP For Not Having Enough Kinetic Energy. That’s Not The Case Anymore. Our 380 Is One Of Our Most Sought After Rounds Because It Packs Enough Punch, It Gets The Job Done.
