PF940SC Polymer 80 Compact Frame Kit

The PF940SC represents a foundational component for builders seeking a reliable, compact pistol platform. As a complete frame kit, this product provides the core structure for a custom firearm build, designed to accept standard Glock 19 and Glock 23 compatible upper parts. The PF940SC frame is precision-molded from high-strength polymer, offering the dimensional stability and impact resistance required for a durable sidearm. This frame is intended for use by individuals who possess the technical skill to complete a firearm build in compliance with all applicable federal, state, and local laws.

Overview

The PF940SC frame is a 80% lower receiver that requires final machining to become a functional firearm frame. It is designed for compact Glock 19 and 23 compatible builds, offering a balance of concealability and magazine capacity. The frame includes all necessary jig and drill bits to complete the pocket and pin holes, allowing the builder to finish the receiver at home using basic tools. This product is sold as a non-functional block of polymer with embedded metal rails, and it is the builder’s responsibility to ensure the finished product complies with all legal requirements. The PF940SC is a direct fit for standard compact holsters and aftermarket grip modules, making it a versatile starting point for a custom pistol.

Who It Is For

The PF940SC frame is intended for experienced firearm builders who have the tools and knowledge to complete a receiver. This product is not for first-time gun owners or individuals unfamiliar with firearm assembly. It is designed for those who want a compact, reliable pistol platform for concealed carry, home defense, or recreational shooting. The PF940SC suits builders who prefer to customize their firearm from the ground up, selecting their preferred slide, barrel, trigger, and sights. It is also appropriate for those who need a spare frame for an existing Glock 19 or 23 build, as it provides a cost-effective alternative to purchasing a complete firearm.

• Experienced builders comfortable with drilling and finishing polymer frames
• Concealed carry practitioners seeking a compact, reliable platform
• Shooters who prefer to customize trigger, sights, and grip texture
• Those who already own Glock 19 or 23 compatible parts for a spare build

Shipping and FFL

This PF940SC frame is classified as a non-firearm item under federal law because it is not yet a functional receiver. As a result, it ships directly to your address without the need for a Federal Firearms License (FFL) transfer. However, it is your responsibility to ensure that completing this frame into a functional firearm is legal in your jurisdiction. Some states and localities impose restrictions on the manufacture of firearms at home, including requirements for serialization or registration. By purchasing this product, you confirm that you are legally eligible to possess a firearm and that you will comply with all applicable laws. We recommend checking with your local law enforcement or legal counsel before beginning your build. No returns or exchanges are accepted on completed frames.
