What Makes It Stand Out
- Compact .40 S&W Platform: The PF940C frame is engineered specifically for the .40 S&W cartridge, providing a robust foundation for a powerful, carry-friendly build.
- Excellent Finish Quality: Our staff noted the finish on our recent batch was excellent, with no visible tooling marks on the polymer frame or metal components.
- Complete Kit: Includes the 80% polymer frame, all required frame parts (rails, pins, locking block), and the dedicated jig for precise completion.
- Proven Reliability: As a long-standing model in the Polymer80 lineup, the PF940C has a track record of reliability when built correctly with quality parts.
- Customization Ready: The completed frame accepts Gen 3 Glock 22/23 slides and aftermarket components, allowing for extensive personalization.

Common Questions
What tools are needed to complete this 80% frame?
You will need a drill press or hand drill, a router or Dremel tool with a milling bit, and standard gunsmithing tools (punches, hammer, files). The included jig provides the necessary guides. Always follow the manufacturer’s instructions precisely.
Does this kit include a slide or barrel?
No. This is a frame kit only. You will need to source a Gen 3 Glock 22 or 23 slide, barrel, recoil spring assembly, and a lower parts kit (LPK) separately to complete a functional pistol.
Is the jig reusable?
The included polymer jig is designed for a single use to complete one frame. For best results and to maintain critical alignment, do not attempt to reuse it on another frame.
