GST-9 Pistol Frame | 80% Arms GST-9 Pistol Build Kit
GST-9 Pistol Frame The GST-9 V1 became a standard for the market for 80% frames when it was first released in November 2019. It offered a modular grip system while still being compatible with Gen 3 G19 parts. With the new GST-9 MOD1 frame , we've lifted the bar once again after three years of customer input and thousands of rounds fired! For improved controls throughout the recoil cycle, the gas pedal's shape and placement were altered. When building out your frame, the grip system was overhauled to ensure a flush fit with grip modules. Last but not least, to substantially facilitate construction, the rear rails were divided into a 2-piece system. FEATURES: A modular frame allows you to use a single 4-in-1 platform to hold weapon systems that are 19, 19X, 19L, and 17 sizes. Compatible with aftermarket parts, holsters, and accessories for the Glock 19 third generation. Only the GST-9 is the first and sole 80% lower that works with Glock holsters. An undercut trigger gua
