Description
The Polymer80 PF940C is the 80% frame for building a Glock 19-sized pistol. It’s for builders who want a custom-fit grip and the satisfaction of a hands-on project. We’ve stocked this frame since Q1 2025, and it’s consistently one of our most popular items, with repeat customers coming back for another build.
What Makes It Stand Out
- Customizable Grip: The frame’s rear strap and undercut trigger guard are designed to be shaped and contoured to fit your hand perfectly.
- Jig-Included Simplicity: Comes with the proprietary jig and required drill bits, providing a clear guide for completing the frame.
- Enhanced Texture: Features aggressive front and rear strap texturing for a secure, non-slip grip right out of the box.
- Rails & Locking Block: Includes the front and rear rail module and locking block for a solid foundation for your slide.
- Proven Design: Uses a familiar, reliable operating system compatible with a wide range of Gen 3 Glock 19 parts and accessories.

Common Questions
What tools do I need to complete this frame?
You’ll need a hand drill or drill press, a Dremel tool or router with a 1/4″ bit for milling, and basic hand tools like files and sandpaper for finishing. The included jig guides the process.
Is this compatible with Glock 19 slides and magazines?
Yes. The PF940C is designed for Gen 3 Glock 19 slides, barrels, and internal parts. It uses standard Glock 19 magazines.
Why do people choose this over a factory frame?
Builders choose it for the ability to customize the grip ergonomics to their exact preference and for the hands-on experience of creating a functional firearm. As one staff member noted, we’ve had customers drive hours just to pick one up—it’s that sought-after for projects.
