GST-9 ORDERS (UPDATED 4/29/2022) 

Thank you for your continued support and patience with us, we are continuing  to ship out our Wraith orders. The good news is that we have the materials in house and we are just going through the process including quality to ensure our products meet our quality standards. 

We are working to ship orders with Wraith Slides and other readily available items. If you have an item that is out of stock, you can always reach out to our support team to split ship any items to get our Wraith order sooner! 

We will continue to release updated shipping timelines to keep you informed. We look forward to seeing everyone's orders being fulfilled! Thank you for your patience and understanding!

Words can not express our gratitude to our customers who stuck with us during this process.

Due to overwhelming demand, and limited resources within the industry on key components, we have decided to temporarily pause the sale of GST-9 Build Kits. This does not affect orders already placed, and we will continue to ship those as fast as we are able. We look forward to making this product live again, but until then, our GST-9 frames are still available for your own custom build!



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 pistol that not only ships straight to your door, but outshoots you everyday of the week. 

Every GST-9 Pistol comes with:

Our products are always backed by our Lifetime Warranty!

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.

How easy is it to build? Check out the instruction manual and see for yourself! 

Shipping Restrictions: This item is restricted from shipping to New Jersey, New York, Hawaii, Connecticut, Rhode Island, Washington D.C., Maryland, Illinois, California, Washington, Boulder Colorado, and Denver Colorado. 

Because the GST-9 is not a firearm, in most cases, it is currently legal to purchase and own an unfinished frame in California. California law prohibits building an off-roster handgun as well as a homebuilt firearm that does not contain an integral 3.7 oz piece of stainless steel. If you are purchasing a GST-9 that ships to California, you certify that you have a law-enforcement exemption, or intend to build and maintain the product outside of the state.
