Looking for a quality 45 Colt self-defense round? You found it. No other round comes close. Far more kinetic energy, less recoil, and less over-penetration. The Civil Defense 45 Colt rounds are built for modern firearms and not recommended for vintage firearms. 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 rupture. With that rupturing comes rifle sized temporary cavities and hydrostatic shock, therefore increasing stopping power by tenfold. Following the rupture, 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 flip for faster follow up shots.
