Polymer80 PF940C™ 80% Pistol Frame Only

If you are looking to build a custom pistol from the ground up, the Polymer80 PF940C™ 80% Pistol Frame Only is where that build begins. This is the compact frame that started the modern 80% handgun movement, and it remains one of the most popular choices for builders who want a reliable, personalized firearm without the full manufacturer serialization. We stock this frame because it offers a genuine hands-on experience for those who understand the mechanics of their tools. Whether you are a first-time builder or a seasoned gunsmith, the polymer80 pf940c™ 80% pistol frame only gives you the foundation to create a pistol that fits your hand and your shooting style.

Overview

This is a raw, unfinished frame that requires you to complete the material removal and assembly yourself. The Polymer80 PF940C™ is designed for Glock 19 Gen3 compatible parts, meaning you can use standard LPKs, slides, barrels, and sights. The frame comes with a 1913 Picatinny rail, an adjustable trigger housing, and a textured grip that feels solid even with sweaty hands. Because it is an 80% frame, it does not require an FFL transfer to purchase, though you will need to finish it into a functional firearm. The polymer80 pf940c™ 80% pistol frame only is the core component for a project that teaches you how your firearm actually works.

Features & Specs

Every feature on this frame is designed for a builder who values function over flash. The frame is made from a high-impact polymer composite that resists cracking and holds up to repeated use. The integrated locking block system simplifies alignment during assembly, and the oversized magwell allows for faster reloads. Here are the key specifications you need to know:

• Manufacturer: Polymer80
• Category: Frames
• Compatible with Glock 19 Gen3 and other Gen3 pattern parts
• Includes jig and bits for completing the frame (some retailers strip these, but we include the full kit)
• Frame color options: black, FDE, OD Green, and gray

The polymer80 pf940c™ 80% pistol frame only also features an ergonomic grip angle that many shooters find more natural than a factory Glock. The trigger guard is undercut for a higher grip, and the rear of the frame includes a beavertail to prevent slide bite. If you are comparing the PF940C to other compact frames, this one stands out because of the integrated rail and the adjustable trigger housing that lets you tweak your trigger pull weight.

• Integrated 1913 Picatinny rail for lights or lasers
• Adjustable trigger housing with overtravel stop
• Textured grip panels on frontstrap, backstrap, and sides

Who It’s For

This frame is for the builder who wants to understand every part of their pistol. It is not for someone looking for a plug-and-play firearm. You need basic mechanical skills, patience, and the right tools to complete the polymer80 pf940c™ 80% pistol frame only. It is ideal for hobbyists who enjoy customizing their firearms, for shooters who want a compact carry gun built exactly to their preferences, or for anyone who wants to learn the function of a striker-fired pistol by assembling it themselves. This frame is also popular among competitive shooters who want a custom grip and trigger for their race gun, and for preppers who value the skill of building their own tools. If you have ever wanted to say you built your own pistol, this is the frame to start with.

Shipping & FFL

Because the Polymer80 PF940C™ 80% Pistol Frame Only is an unfinished frame, it does not meet the legal definition of a firearm under federal law. This means it can be shipped directly to your door with no FFL transfer required. However, once you complete the frame into a functional pistol, you must comply with all federal, state, and local laws regarding possession, serialization, and use. Some states and localities have laws specifically regulating 80% frames and unserialized firearms. It is your responsibility to know and follow the laws in your area before purchasing the polymer80 pf940c™ 80% pistol frame only. We ship to all US states where this product is legal, and we do not ship to PO boxes. All orders are processed within one business day, and tracking information is emailed to you as soon as the package leaves our warehouse.
