Is this kit compatible with both .45 ACP and 10mm?
Yes, absolutely. The PF45 frame is uniquely designed to accommodate both .45 ACP and 10mm caliber builds. The critical difference lies in the parts kit you select to complete your firearm. You will need to source a Glock 20-style parts kit for a 10mm build or a Glock 21-style kit for a .45 ACP build, as the slides, barrels, and magazines are caliber-specific. The PF45 frame itself is the versatile foundation for either powerful cartridge.
What tools are required to complete the 80% frame?
Completion requires a standard hand drill or drill press, a 3/8″ end mill bit for the fire control pocket, and common workshop safety equipment. The included jig provides precise guidance for all drilling operations. While the process is straightforward for those with moderate mechanical aptitude, patience and careful attention to the instructions are crucial for achieving a flawless, reliable final product. We recommend using a vise to securely hold the jig during milling.
Is the finished frame compatible with OEM Glock parts?
The PF45 frame is designed to be compatible with Generation 3 style Glock 20 (10mm) and Glock 21 (.45 ACP) factory components and aftermarket parts kits. This includes slides, barrels, recoil spring assemblies, and lower parts kits. However, due to variances in aftermarket manufacturing, we always recommend verifying compatibility with your chosen components. The frame uses standard Glock-pattern magazines for its respective caliber.
Do I need an FFL or background check to purchase this kit?
No. This 80% frame kit is not considered a firearm under federal law and ships directly to your door with no FFL (Federal Firearms License) transfer required. It is the builder’s responsibility to complete the frame in compliance with all federal, state, and local laws. Upon completion, the builder creates a firearm for personal use, subject to all applicable regulations. Always check your state and municipal laws before ordering.
