Polymer80 PF940C 80% Pistol Frame – 3-Pack

If you are looking to build from the ground up, the Polymer80 PF940C 80% Pistol Frame – 3-Pack gives you three solid starts for your next custom project. Each frame is an unfinished lower receiver that requires final milling and drilling, putting the build process directly in your hands. This is not a complete firearm, but a foundation that lets you choose your own slide, barrel, trigger, and grip texture preferences. For builders who want to work in batches or keep spare frames on hand, this three-pack offers solid value without cutting corners on material quality.

Overview

The PF940C is a compact frame designed around the Glock 19 platform but with several ergonomic improvements straight from Polymer80. The frame features a built-in accessory rail, an aggressive texture pattern on the grip, and a slightly reshaped trigger guard for better high-hand placement. Because these are 80% frames, you will need to complete the material removal in the rear rail pockets, trigger housing area, and pin holes before assembly. Each frame in this pack is identical in its unfinished state, so you can expect consistent work from the first frame to the third. The polymer material is a reinforced, impact-resistant blend that holds up well under recoil and resists flex during the machining process.

Features & Specs

• Unfinished 80% compact frame compatible with Glock 19 Gen1 through Gen3 parts kits, slides, and barrels; requires drilling and milling to complete
• Integrated Picatinny-style accessory rail for lights or lasers; textured front and rear grip surfaces with finger grooves removed for a more customizable grip feel
• Reinforced polymer construction with stainless steel rear rail system (rails included with each frame); oversized trigger guard accommodates gloved hands

Each of the three frames includes the necessary jig, drill bits, and end mill to complete the work. The frame channels are pre-molded but still require clean-up passes to ensure smooth operation of the slide and trigger components. The included jig is reusable, so you can work through all three frames without needing additional tooling. The frames are made in the United States and are not serialized at the time of purchase, meaning you are responsible for marking the frame as required by local laws.

Who It’s For

This three-pack is ideal for the hands-on builder who wants to experiment with different slide configurations or grip modifications across multiple frames. If you are the type of person who likes to test different trigger weights, barrel lengths, or optic cuts without committing to a single build, having three frames lets you set up a compact pistol, a competition variant, and a backup all from the same starting point. It also suits instructors or shop owners who demonstrate the 80% build process to students or customers. Because the frame is compact, it works well for concealed carry setups once completed, but the builder should have at least intermediate experience with hand tools and a steady hand for the drilling steps. This is not a beginner project if you have never worked on a firearm frame before, but the included jig makes the process repeatable.

Shipping & FFL

Because the Polymer80 PF940C 80% Pistol Frame – 3-Pack is not a finished firearm and does not contain a serialized receiver, it can be shipped directly to your home or business address in most states. No transfer through a Federal Firearms License (FFL) dealer is required for the frame itself. However, you are solely responsible for understanding and complying with all state and local laws regarding the possession and completion of unfinished frames. Some states and municipalities restrict or prohibit the ownership of 80% frames or require serialization upon completion. By purchasing this product, you acknowledge that you will follow all applicable laws in your jurisdiction. We do not provide legal advice, and you should consult an attorney if you have questions about your local regulations. Shipping is via UPS or FedEx ground, and signature may be required at our discretion.
