Design and Materials

Arex engineered the GO AREX ZERO 1 S 9MM with a 4.25″ cold hammer forged barrel for durability and consistency shot-to-shot. The frame uses black hardcoat anodized 7075 aluminum, a choice that balances strength and weight for extended carry or duty use. Three-dot steel sights provide a robust, snag-resistant sight picture suitable for low-light transitions and rapid target acquisition.

Magazine and Capacity

The pistol ships with two 17-round magazines, giving ample capacity for training and defensive scenarios without aftermarket modification. Standard high-capacity magazines paired with a reliable feeding system support extended range sessions and duty-level readiness.

Performance & Reliability

Built to meet strict military standards, the GO AREX ZERO 1 S 9MM has passed extreme temperature and hostile environment testing as well as drop tests. Expect a service life exceeding 30,000 rounds when maintained to factory recommendations — a metric that highlights long-term durability and lowers lifecycle cost for teams and dedicated shooters.

Why 9mm?

9mm is a practical defensive caliber: controllable recoil, wide ammunition availability, and favorable magazine capacity. For tactical roles, the balance of terminal performance and shootability makes 9mm the logical choice for most users operating in close-quarters defense and duty carry profiles.

Arex, in partnership with FIME Group of Las Vegas NV, positions this model for sport, tactical shooting, self-defense, and potential agency adoption. For users prioritizing a proven lifecycle, steel sights, and a hardened aluminum frame with a cold hammer forged barrel, the GO AREX ZERO 1 S 9MM is a capable option.
