Compared To Other Top Self-Defense Rounds

The Civil Defense 357 Sig is one of our best rounds for self-defense. It has more kinetic energy than most 45 ACP self-defense rounds but only weighs as much as standard 9mm rounds. The 357 Sig is a very underappreciated caliber. Our lead-free 357 Sig goes 2300 FPS out of a 4″ barrel. A feat that has never been done before in guns you can comfortably carry concealed. 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 things considered, it’s the best 357 Sig round for self-defense and it’s lead-free.

Liberty only.

357 Sig Liberty round is the ultimate pistol cartridge. Puts recoil back in the hand, reducing muzzle flip, with extreme speed and power behind a bullit that doesn’t overpenetrate Hats off to

LIBERTY!

Thanks David,

Our .357 Sig is the best .357 on the market.

We appreciate your kind words.

Impressive

Tested through a P229 with 3.9 inch barrel and got 2205fps average, which I calculate to 541 ft/lbs. It’s like a laser beam. I have a 16 inch barrel 357 SIG carbine and got an average of 2780fps, which I calculate to 858 ft/lbs. I haven’t tested for accuracy over distance, yet. I’ve tested a bunch of bullets and only one even comes close on energy, so far.

Andy, thanks for the note.

WOW!

2750 fps is crazy fast and will hit harder than any other brand.

A little loud but a whole lot of LIGHTER recoil. AMAZING AMMO

I love this 357 Sig ammo out of my G35 threaded conversion barrel. The reduced recoil is so drastic it is almost funny. Follow up shots are faster due to the light recoil. It really is VERY noticeable.

This is the only self-defense ammo I will be running now. I am going to purchase more and more in every caliber I have. I am a LEO and would love to switch to this on duty. That’s how impressed I am!!!

The magazines are lighter, and ounces make pounds! Functioned flawlessly in a BRAND-NEW drop-in barrel too. I really can’t say enough good things about this ammo.

PS-I RARELY leave reviews, but this ammo/company deserved it. Thank you, Liberty. I am looking forward to purchasing more and more.

Until I discovered Liberty, I’d been carrying Federal Hydra-Shok. After changing my EDC to a Glock 32.4, I searched and found Civil Defense for .357Sig. Awesome. I fired a box to get a feel for the round; completely controllable and highly accurate. Civil Defense is all I carry now.

Power and accuracy higher than advertised!

I have Civil Defense in several calibers. They cycle better and smoother than other manufacturers due to their consistency and excessive polishing! My chrono has them out of the muzzle at 2324avg. out of a factory Sig 2022. Amazing accuracy!

Best self-defense 10mm/9mm on the market

July 7, 2025

About 6 years ago I bought my first 10mm, Rock Island Armory 10mm A2 FS HC , for self defense and bear country EDC. I bought 43 different types of ammo from every big and small company i could find to begin testing what I would carry for self defense against 2 and 4 legged threats. 3 different types of target scenario was setup, it took me 3 days to test each one maticuosly and with a broad assortment of ammo types amd weights I ended up picking the Liberty Civil Defense as my EDC ammo even though i thought it was a gimmicky round when I purchased it for the very first time, I even switched my back up 9mm to this brand…I will never trust any other round on the market with my or my family’s life on the line like I do with this ammo. The ONLY negative I can possibly point out, is you will always need to double tap if there is glass between you and the target, almost all other normal scenario barriers are no match. This round will penetrate through dense objects (such as a 6 inch polymer pillar that is hollow in the center) further than most FMJ or Hard Cast. If your in doubt…TRY IT OUT, you’ll ditch the gold dot/hydrashok/R.I.P forever

I’ve purchased a few different calibers quite awhile back to choose one for self defense and my concern was truly bullet weight and at the range that problem was resolved quickly by a mere few shot. I found these rounds devastating and all three calibers I would feel very safe using anyone of them for self defense. In closing I would hate getting hit with one of these rounds, however I’m a law biding citizen.

Light, fast and devastating

July 7, 2025

I happened to come across a couple boxes of this wonderful ammo at my local indoor range, and decided to get a couple boxes to test in my Sig P220 Legion.

During the test I fired the Overwatch along with some Hornady Critical Duty w/ the 175Gr FlexLock and some Hornady Custom 155Gr XTPs.

First impression with the Overwatch is that it’s so light; it’s barely noticeable once the loaded mag is in the pistol because it’s so light.

The Overwatch is louder than the range rounds or the Hornady rounds I fired, but felt recoil is noticeably reduced.

Accuracy compared to the Hornady was perhaps a tad better due to reduced felt recoil at 10-25 Yards.

I had zero FTFs or any issues at all with the Overwatch; it cycled through my Sig flawlessly.

I cannot speak to the stopping power of this round since I’ve only punched holes in paper with it, but tests I’ve seen online are very interesting indeed.

I now plan to carry my Sig with Overwatch due to the great performance and low weight!

CM,

Thanks for the review.

We are lighter to carry and hit harder than the other brands.

We also create a permanent wound channel compared to softer hitting Hornady rounds.

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.
