Grab a frame blank to start your 80% GLOCK build.
To assemble your GLOCK® kit, you need one of these 80% GLOCK® frames. Produced by Polymer80 and commonly called "P80 frames", these firearm blanks are compatible with Generation 3 and newer GLOCK® components, including factory and aftermarket GLOCK parts.
These frames are non-functional, and unfinished. They're considered firearm frame blanks, which means they cannot accept the components necessary to make them into working firearms. You, the builder, must finish fabricating the frame. Once fabrication is complete, your frame is considered a firearm under federal law, and it can accept parts like a barrel, slide, trigger, and the pins and springs needed to function.
Our available GLOCK build kits include all the parts needed to assemble your finished frame. Magazines are sold separately.
These polymer80 frames are compatible with certain factory GLOCK® handgun models. Choose the frame option below, based on the model and caliber you wish to fabricate and assemble.
Read our frame compatibility guide to learn more about these frames, and their GLOCK models and calibers.
Each 80% GLOCK frame includes a locking block rail component, and rear rail module. These two parts are required for final assembly, and work with the components you'll also need to use to assemble your frame with its corresponding GLOCK build kit.
No other assembly components are included. No drill bits, jig, or other tooling required to complete each frame is included, either -- they are sold separately.
Some states have banned 80% frames and certain firearm parts, or have otherwise restricted the sale and ownership of products we sell. So, be sure to check your local and state laws. We can’t ship our products to certain states. Please check our Shipping & Return Policy before placing an order (see restrictions).
