ETS magazines are engineered from advanced polymer materials that deliver exceptional durability and reliability. The clear polymer body lets you quickly verify your round count at a glance—a practical feature for range sessions and defensive training.
These magazines won't crack or break when dropped on hard surfaces. The advanced polymer formulation resists impact damage that would compromise lesser magazines, making them ideal for shooters who demand dependable equipment in real-world conditions.
ETS magazines maintain their integrity across extreme temperature ranges. They won't become brittle in harsh cold or degrade when exposed to chemicals and environmental contaminants. This stability ensures consistent performance whether you're shooting in desert heat or winter conditions.
The durable construction eliminates feed lip and body creep—a common problem with long-term storage of fully loaded magazines. Your ETS magazine will maintain its shape and feeding reliability indefinitely, even when stored loaded.
