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.
