The GST-9 is the world’s first truly modular 80% pistol frame system compatible with Glock® 19 Gen 1-3 platform components. Patent-pending modular grips allow for easy conversion between compact and full-size frames. Ergonomics have been improved by designing a contoured grip that improves comfort and allows you superior control. An undercut trigger guard gives you a higher grip on the frame, lowering the bore-axis and reducing muzzle flip for faster, more accurate follow-up shots.
The GST-9 features several functional improvements over the time-tested Glock® platform, starting with the mating surface between the slide and frame. Frame rails have been extended three times their normal length for more repeatability, better accuracy, and controlled recoil impulse. Nickel plating improves reliability by reducing friction between moving parts in the harshest conditions, even after liquid lubricants have long since cooked off.
Not only is the GST-9 the most effective 80% pistol yet, it’s also the easiest 80% pistol to build. We drew upon our expertise as the world leader in jig design to solve the shortcomings of other jigs on the market. Using a five-point clamping mechanism, significantly beefed up drill guides, and a body made of 3x stronger glass-filled polymer, it’s the easiest and most precise pistol jig ever. All of this means that you aren’t just getting the best 80%, Glock-compatible frame on the market, but you can finish it in minutes.
