GST-9

INTRODUCING... THE GST-9

Introducing the GST-9, the world’s first modular polymer 80% pistol compatible with Generation 1-3 Glock® components and both Glock® 17 and Glock® 19 magazines. Engineered from the inside out to improve upon the original Glock® design, the GST-9 frame is packed with features not found anywhere else. We spent two years studying customer feedback to determine what features were missing among the different options, and not only incorporated what we found, but we gave you the option to choose how to build each frame.

GST-9 offers multiple grip modules for both a standard and a full-size frame that quickly attach to the contoured frame for improved ergonomics and shootability. Flared magwells speed up reload times, and our ultra-slick nickel-coated rails which are three-times original OEM length keep tolerances tight and recoil managed for quick, precise shooting.
