Polymer80 PF940C 80% Pistol Frame – 3-Pack

If you are looking to take on a rewarding weekend project or stock up for future builds, the Polymer80 PF940C 80% Pistol Frame – 3-Pack delivers exactly what a hands-on builder needs. Each frame in this pack is the PF940C compact model, designed to accept standard Glock 19 Gen3 parts kits. Because these are 80% frames, they require you to complete the final material removal on the trigger housing pocket and pin holes. This gives you the satisfaction of finishing your own firearm without the need for a serial number, as these frames are not yet classified as firearms by the ATF. For the serious enthusiast, buying the polymer80 pf940c 80% pistol frame – 3-pack saves time and ensures you have matching frames for multiple builds right out of the box.

Overview

The Polymer80 PF940C is one of the most popular platforms for DIY pistol assembly. Its compact size fits comfortably in hand while accepting standard compact magazines, and the 80% design means you get to handle the key machining steps yourself. This 3-pack is ideal for builders who want to experiment with different configurations, offer frames to friends, or simply keep spares on hand. The frames are made from a high-impact, glass-reinforced polymer that resists flexing and holds up under hard use. Every frame in this pack includes the necessary jig and drill bits to complete the work, so you can start building as soon as it arrives.

Features & Specs

These frames are built with the same attention to detail as Polymer80’s more expensive options, but without the serialized components. Here is what you get with each frame in the polymer80 pf940c 80% pistol frame – 3-pack:

• Acceptance of standard Glock 19 Gen3 slide and lower parts kits, including trigger, magazine release, and slide lock.
• Integrated accessory rail for lights or lasers, compatible with most universal pistol rail attachments.
• Aggressive texture on the grip and finger grooves for a secure hold, even with wet hands or gloves.

From a spec standpoint, each frame is pre-molded with the front and rear rail modules installed. The only work required is removing the remaining polymer from the trigger housing area and drilling the pin holes using the included jig. The frame is compatible with standard compact holsters once assembled, and the magazine well is slightly flared for faster reloads. This 3-pack gives you three identical frames, so your builds will feel consistent from one to the next.

Who It’s For

This product is for the intermediate to advanced builder who understands the mechanics of a pistol and is comfortable using basic hand tools like a drill press or hand drill. If you have already assembled a few AR-15 lower receivers or worked with other 80% frames, you will find the PF940C straightforward and rewarding. It is also a great option for instructors or clubs that want to teach pistol building classes, as the 3-pack keeps costs down per frame. Beginners are welcome, but we recommend watching a few build videos first to understand the process. This frame is not for someone looking for a complete, ready-to-fire pistol out of the box. Instead, it is for the person who wants to say, “I built this myself.”

Shipping & FFL

Because the polymer80 pf940c 80% pistol frame – 3-pack is not a firearm under federal law, it ships directly to your doorstep with no FFL transfer required. There is no background check, no waiting period, and no need to involve a dealer. However, you must be at least 21 years old and legally allowed to possess firearm components. We recommend checking your state and local laws before ordering, as some jurisdictions have specific restrictions on 80% frames. Once your frames arrive, the work is entirely up to you. We ship via UPS Ground with adult signature required for all frame deliveries. If you have any questions about compatibility or build instructions, our support team can help guide you through the process.
