The complete GST-9 pistol kit is everything you need to build a top-tier handgun, at a production level price. Engineered from the ground up to capitalize on all the strengths of the Generation 1-3 Glock® platform, while also incorporating the most common aftermarket upgrades as standard features, we've created a product that not only ships straight to your door, but also offers unparalleled performance and reliability right out of the box, eliminating the need for further modifications or adjustments. 

Every GST-9 Pistol comes with:

 

Our products are always backed by our Lifetime Warranty!

Due to 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.
