Our Ultra-Light projectiles function differently than any other self-defense round on the market. We designed the Civil Defense/Ultra-Lights 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.
