Taking your PF940C from a raw frame to a functional firearm is a deeply satisfying project. The design prioritizes a natural point of aim and features aggressive front and rear strap texturing for superior control. The frame accommodates a vast aftermarket of slides, barrels, and internal components, letting you tailor trigger pull, sighting systems, and aesthetics to your exact specifications. This kit is about more than assembly; it’s about creating a truly unique tool that reflects your understanding of firearm mechanics and personal ergonomic needs.
What tools are needed to complete this 80% frame?
You will need a Polymer80-specific jig (sold separately), a reliable drill press or hand drill, various drill bits, and quality hand tools like files, sandpaper, and punches. A Dremel tool with milling bits can expedite the process but is not strictly required. Always follow the official Polymer80 instructions precisely for a safe and proper build.
Is this kit compatible with Glock® 19 magazines and parts?
Yes. Once completed, the PF940C frame is designed to function with standard Glock® 19 Gen 3 pattern slides, barrels, upper and lower parts kits, and magazines. It is always recommended to use quality, in-spec components from reputable manufacturers to ensure reliability.
Do I need an FFL or background check to purchase this?
No. Because this is an unfinished 80% receiver/frame, it is not considered a firearm under federal law and can be shipped directly to your door without an FFL transfer. However, you must be legally eligible to possess a firearm, and you are responsible for knowing and complying with all state and local laws regarding the manufacture of personal firearms.
What is the difference between the PF940C and the PF940v2?
The primary difference is size and compatibility. The PF940C (Compact) is designed for Glock® 19-sized components, resulting in a more concealable pistol. The PF940v2 is the full-size frame compatible with Glock® 17 components. Both share the same high-quality construction and building process but cater to different size preferences.
