Each 1.8-gram round is designed to fit perfectly in T4E models such as Walther PPQ/ TPM1 And Glock17/G17 Gen 5, 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.
