ATI GSG-9 | 9mm | 7.5" | Brace | 33rd Pistol

The ATI GSG-9 (MPN: GERGGSG933) is a rugged, versatile, and highly modular 9mm large-format pistol designed for shooters who demand a high-performance PDW (Personal Defense Weapon) with unmatched magazine flexibility. Built with a focus on cross-platform compatibility and extreme durability, the GSG-9 features a heavy-duty all-aluminum upper receiver and a factory-installed stabilizing brace, making it an ideal choice for home defense, vehicle carry, or high-volume range sessions.

Industry-Leading Magazine Interoperability

The standout feature of the GSG-9 is its unique modular magazine well system. This package includes two interchangeable magazine adapters, allowing you to switch between Glock-style 9mm magazines and Sig Sauer P320 9mm magazines in seconds. Whether you carry a G17 or a P320 as your sidearm, the GSG-9 ensures your primary and secondary platforms share the same logistical backbone, giving you total tactical flexibility without needing proprietary mags.

Modern PDW Ergonomics

The GSG-9 is engineered for professional-grade handling. It features a non-reciprocating charging handle that can be swapped to either the left or right side, catering to both right and left-handed shooters while ensuring the handle stays stationary during the firing cycle. The 7.5-inch barrel provides increased 9mm ballistics and is capped with a threaded muzzle for easy suppressor or muzzle device integration. The included stabilizing brace offers a solid point of contact for improved accuracy, ensuring the GSG-9 remains controllable even during rapid fire.
