The ETM started with a blank sheet of paper and 30+ years of 1911 and 1911 magazine experience. The ETM is no re-design of a 7 round magazine which has been reconfigured for 8 round capacity; its a totally NEW product designed from the ground-up as a premium 8 round tactical magazine. It WILL set a new standard in 1911 magazines while redefining state-of-the-art. Weve blended the latest improvements in manufacturing and materials technology with our own real-world shooting experience to provide quality, quality, and more quality. From material selection to manufacturing process to final testing this magazine is built like your life, and ours, depended on it, as someday it may. No compromises, just stone-cold reliability you can depend on. The ETM is primarily a combat magazine, but if youre a competition shooter, you just may gain that critical advantage that will move you past the competition.
