Each 2.8-gram round is designed to fit perfectly in T4E models such as TR50, HDP50 or Alfa, providing excellent consistency and power for serious home defense needs. Heavier than traditional rubber or nylon options, these aluminum rounds offer improved penetration and impact, setting a new standard in self-defense ammunition. These aluminum balls deliver enhanced precision and longer flight distances, making them ideal for both defensive use and target practice. When used with a well-oiled setup, they perform at their best, with reduced wear on your weapon's internals. We recommend pre-oiling each ball with silicone spray to maximize performance.
