Liberty Ultra-Light 9mm Luger +P 50gr HP Handgun Ammo – 20 Rounds – Liberty created a whole new monster with the 9mm+P Ultra-Lights. They combined their innovative Civil Defense projectiles with Shell Shock Tech’s groundbreaking new cases to create the ultimate self-defense rounds. It has more kinetic energy than a lot of 45 ACP self defense rounds, except it’s more convenient than any self-defense round in today’s market. Liberty’s projectiles function differently than any other self-defense round on the market. They designed the Civil Defense/Ultra-Lights to eliminate threats with one round. They 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 flip for faster follow up shots. Less Felt Recoil More Velocity and Kinetic Energy Reduced Over-Penetration More Stopping Power Less Weight
