Polymer80 PF940C 80% Pistol Frame – 3-Pack

If you are looking for a solid foundation for your next build, the polymer80 pf940c 80% pistol frame – 3-pack offers a practical way to stock up on quality frames. This three-pack gives you the raw material to complete multiple projects, whether you are building for personal use or experimenting with different configurations. Each frame requires finishing work, which means you get to control the final fit and feel. Below, we break down what these frames offer, who they suit best, and what to expect once they arrive.

Overview

The PF940C is a compact-sized 80% frame designed to accept standard Glock 19 Gen 3 parts. It comes as an unfinished block of polymer with the main structure molded in, but without the fire control pocket, trigger housing pin holes, and rear rail module channel fully machined. This means you will need to complete these areas yourself using basic hand tools and a drill press or jig. The three-pack includes three identical frames, each with stainless steel front and rear rail modules pre-installed, which simplifies the build process compared to older 80% designs. For anyone who values hands-on work, this is a straightforward way to produce multiple finished frames without needing a full machine shop.

Features & Specs

These frames come from Polymer80, a well-known manufacturer in the 80% community, and they fall under the category of unfinished frames. Here is what you get with each unit in the three-pack:

• Compact frame geometry compatible with Glock 19 Gen 3 slides, barrels, and lower parts kits
• Integrated trigger guard undercut and a beavertail for improved ergonomics
• Stainless steel front and rear rail modules already installed and pinned in place
• Picatinny accessory rail on the dust cover for lights or lasers
• Requires finishing the fire control pocket, drilling three pin holes, and channeling the rear rail module area

Each frame is made from a reinforced polymer that resists flex under recoil. The texture on the grip is moderate, so you may want to add stippling or grip tape for a more aggressive hold. Because these are 80% frames, there is no serial number, and you are responsible for completing the work within legal boundaries for your state and local laws.

Who It’s For

The polymer80 pf940c 80% pistol frame – 3-pack is ideal for builders who want to produce multiple frames at once, especially if you plan to gift completed frames to family members (where legal) or simply want backups in your workshop. It suits intermediate-level builders who have some experience with 80% frames or are comfortable following a detailed build guide. If you have already built a PF940C and want to refine your technique, the three-pack lets you practice without buying individual frames each time. Beginners can also use this pack, but expect a learning curve on the first frame. The compact size works well for concealed carry or range use, and because you finish the frame yourself, you can tune the trigger feel and fit to your preference.

Shipping & FFL

Because these are 80% frames, they are not classified as firearms by the ATF and do not require transfer through a Federal Firearms License (FFL) holder. However, we still require you to confirm that you are legally allowed to possess and complete such frames in your jurisdiction. Some states and localities have specific restrictions on unserialized frames or require serialization after completion. It is your responsibility to check local laws before ordering. We ship directly to your doorstep via UPS or FedEx, and you must be 18 or older to purchase. No signature is required, but we recommend using a secure shipping address. Once the frames are completed, you may need to comply with state-specific laws regarding serial numbers and background checks for the finished firearm.
