Polymer80 PF940C 80% Pistol Frame – 3-Pack

If you are looking to build a compact 9mm or .40 S&W pistol from the ground up, the Polymer80 PF940C 80% Pistol Frame – 3-Pack offers a solid foundation for your next project. These frames are designed for builders who want hands-on control over their firearm’s ergonomics and trigger feel without the need for a serialized, fully finished receiver. Each frame in this pack requires basic finishing work to complete, giving you three separate builds or spares for future projects. With a compact grip profile, these frames are well-suited for concealed carry or range use, and they accept a wide range of Gen3-compatible parts.

Overview

The Polymer80 PF940C 80% Pistol Frame – 3-Pack is a cost-effective solution for the dedicated DIY builder. Each frame is made from a high-strength, impact-resistant polymer that mirrors the dimensions and geometry of standard compact frames, but without a serial number or a fully machined fire control cavity. You will need to complete the milling and drilling steps yourself to finish the frame for assembly. This pack is ideal if you want to experiment with different slide and barrel combinations, or if you simply want a backup frame ready for your next build. Because these frames are uncompleted, they ship directly to your door with no FFL transfer required for the frame itself.

Features & Specs

Each frame in the Polymer80 PF940C 80% Pistol Frame – 3-Pack is engineered for reliable function and a comfortable grip. The compact design fits most standard holsters and magazines, and the integrated rail system allows for easy attachment of lights or lasers. Here is a quick look at what you get with each frame:

• Manufacturer: Polymer80. Category: Frames. Compatible with Gen3 Glock-style slides and parts.
• Compact frame size with a 15-round magazine capacity (9mm) and a textured grip surface.
• Includes all necessary jigs, drill bits, and instructions to complete the frame at home.

The finishing process requires patience and basic tools, but the included jig keeps alignment precise. Once completed, you will have a fully functional, serial-number-free frame that is ready for your chosen slide, barrel, and lower parts kit. The 3-pack gives you three identical platforms, making it easy to build matching pistols or share with a trusted friend who is also a DIY enthusiast.

Who It’s For

This 3-pack is built for the hands-on hobbyist who enjoys the process of building as much as shooting. If you have some experience with firearm assembly or are willing to learn, the Polymer80 PF940C 80% Pistol Frame – 3-Pack is a great fit. It is not for someone looking for a ready-to-shoot pistol out of the box, as each frame requires finishing work. However, if you want to customize your grip angle, trigger weight, and slide finish from the ground up, this pack gives you three opportunities to do so. It is also a practical option for those who want to build a dedicated home defense pistol and a separate range gun without buying multiple serialized frames. Because these are 80% frames, they are not considered firearms by the ATF, so you can order them without a background check, but you must comply with all local, state, and federal laws regarding completion and ownership.

Shipping & FFL

Because the Polymer80 PF940C 80% Pistol Frame – 3-Pack is an unfinished frame, it is not classified as a firearm and can be shipped directly to your residence without a Federal Firearms License (FFL) transfer. However, you are solely responsible for understanding and complying with all local, state, and federal laws before purchasing, completing, or assembling this frame. Some states and localities have specific restrictions on 80% frames or require serialization once completed. It is your responsibility to verify legality in your jurisdiction. No FFL transfer is required for the frame itself, but any completed firearm built from this frame must comply with all applicable laws, including any requirements for serialization or registration. By purchasing this product, you confirm that you are legally allowed to own and build firearms in your area.
