GST9: MOD1, Limited Edition White Frame

LIMITED WHITE FRAME: This is our limited edition white frame! We have a small stock quantity of these, and depending on demand, we may or may not get more small batches in the future! Each one of these frames comes with BOTH the Compact, and the Full-Size, grip modules. Build a stormtrooper style pistol, or RIT dye any color you desire! This frame offers ultimate customization.

Please note, these frames will show dirt and carbon easily from dirty hands and from burnt gunpowder. All sales of this product are final.

Released in November 2019, the original GST-9 took the 80% world by storm, offering modular enhancements to a Glock style frame without losing any parts compatibility. Two years and hundreds of thousands of rounds downrange later, we’ve raised the bar again with the GST-9 Mod 1.

What makes the GST-9 Mod 1 version so special?

  • Modular frame gives you a 19, 19X, 19L, & 17 size weapon system in a single 4-in-1 platform
  • Compatible with Glock 19 3rd generation parts, holsters, & aftermarket accessories. GST-9 is the first and only 80% lower that is compatible with Glock holsters
  • Ergonomic features include a single undercut, high beavertail, glove bevel, scalloped mag release, no finger grooves, & newly redesigned gas pedals as standard
  • Premium internal rail components extended 3X, made of stainless steel, with multiple coating options
  • Easily ships to your door & completes in minutes

With two years feedback from our customers under our belts, we made a few changes to our GST-9 frame to stay ahead of the curve in an ever-competitive 80% Glock parts market. First, we relocated the gas pedals forward, and re-contoured them to further optimize control over the frame through the recoil cycle, always helping to drive the gun back to target faster and more efficiently. We also re-contoured our modular grip attachment surfaces so that every grip option gives you a perfect fit, for the cleanest build possible. Internally, we’ve now separated the rear-rail module to improve the build process, with users now only needing to line up one hole at a time, eliminating rail flex during install.

The GST-9 Mod 1 is built from the ground up to be reliable, customizable, and shootable. It’s the most functional and user-customizable 80% Glock compatible frame on the market. And, like all of our products, is backed by our Lifetime Warranty, and our premium customer support.

*The GST-9 does NOT accept Glock 17 slides. The GST-9 frame accepts Glock 19, Glock 19L, & Glock 19XL slides*

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 our 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.
