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.
