The GST-9 embodies the 2nd Amendment spirit, offering a top-tier polymer 80% pistol frame that's seamlessly compatible with Glock® 19 Gen 1-3 components. With its patent-pending modular grips, users can easily transition between a compact or full-size frame. The contoured grip design prioritizes comfort and control, while the undercut trigger guard allows for an optimized grip on the frame, reducing muzzle flip and ensuring faster, more accurate shots. Each frame comes standard with a compact grip module. The full-size grip is available separately for purchase.

Building on the Glock® platform, the GST-9 introduces several enhancements. The connection between the slide and frame has been refined, with frame rails extended to triple their usual length for improved accuracy and controlled recoil. The addition of Nickel-Boron plating boosts reliability, reducing friction between moving parts, even in challenging conditions.

The GST-9 is not just innovative but also user-friendly. Drawing from expertise in the 80% industry, it's designed for ease of assembly. The V1 GST-9 jig is designed with a robust five-point clamping system, enhanced drill guides, and a body made from US glass-filled polymer make it straightforward and precise.
