We’ve created a whole new monster with the 9mm+P Ultra-Lights. We’ve combined our 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. – Weight: 50gr – Velocity: 2040 FPS – Kinetic Energy: 462 FPE – Accuracy: < 1 @ 25 Meters – Rounds: 20 per box – Terminal Effect: 3 ½ W x 12 D – Compared To Other Top Self-Defense Rounds – Our 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. 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 fewer muzzle flips for faster follow-up shots. The cases are a two-piece nickel alloy shell with an aluminum base that is twice as strong as brass and only half the weight. Shell Shock's NAS3 9mm cases are 50% lighter than brass cases offer greater lubricity and will not abrade clog foul wear-out or damage breach and ejector mechanisms. The cases offer greater corrosion resistance higher tensile strength (2x stronger) and more elasticity than brass. NAS3 cases have been tested successfully to pressures over 50k psi. NAS3 cases eject cool to-the-touch and can be picked up with a magnet.
