The GST-9 is the world’s first truly modular 80% pistol frame system compatible with Gen 1-3 Glock® 19 platform components and Glock® holsters. Patent-pending modular grips allow for easy conversion between compact and full size allowing for the use of both Glock® 19 and Glock® 17 magazines. Ergonomics have been improved by designing a contoured grip that improves comfort and helps tame recoil. An undercut trigger guard gives you a higher grip on the frame, thus 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 a dramatically improved 80% Glock® parts compatible pistol frame design, but it’s also the easiest 80% pistol to build. The GST-9 jig uses a much stronger clamping mechanism, significantly beefed up drill guides, and a glass-filled polymer material that is 3x stronger than the plastic used in every other polymer lower jig. This decreases lower completion time, lowers the chances of messing up your build, and results in a much more precise finished lower. You can expect to complete your GST-9 build in only about 10 minutes.
Due to recently changed ATF regulations, we cannot legally include the jig or frame rails with the GST-9 frame. The jig and GST-9 frame must be purchased on the website as two separate items. Each jig includes one set of GST-9 frame rails. You will need to purchase one jig for every GST-9 frame you plan to build. Frame rails are ONLY included with the jig, not with the 80% lower itself.
