The Polymer80 PF940v2 80% Frame Kit is the foundational component for building a custom Glock 17/22/31 pattern pistol. It’s designed for the experienced hobbyist who values a hands-on project and understands the legal requirements for 80% builds. This model has been a steady seller for us since we started stocking it, and our staff uses it in our shop’s demo Glock for function testing.
Stand-Out Features
- Jig-Included Design: The proprietary jig system is included, providing the necessary guides for precise milling and drilling operations to complete the frame.
- Enhanced Grip Geometry: Features a more aggressive texture and a redesigned undercut trigger guard for improved hand placement and control compared to OEM frames.
- Serial Number Area: Includes a pre-milled, flat section on the frame rail for applying a serial number, in compliance with federal regulations if you choose to serialize.
- Durable Polymer Construction: Made from reinforced polymer for a lightweight yet robust frame that handles standard Gen 3 Glock components.
- Complete Kit: Comes with all necessary frame parts, including the locking block, rear rail module, and pins, minimizing the need to source additional hardware.

Your Questions Answered
What tools are needed to finish this 80% frame?
You will need a drill press or a sturdy hand drill, a vise, and a milling tool (like a Dremel with router base or a compact router) to remove the polymer tabs and complete the fire control cavity. The included jig provides the necessary guides. Basic workshop safety equipment is also required.
Is this legal to purchase and build?
Under federal law, this 80% frame is not considered a firearm and can be shipped directly to most customers. However, state and local laws vary significantly. It is the purchaser’s responsibility to know and comply with all applicable laws in their jurisdiction regarding the purchase, completion, and possession of an 80% frame. We do not ship to restricted states.
Does this work with aftermarket slides and barrels?
Yes. Once properly completed, the PF940v2 frame is designed to accept standard aftermarket and OEM Glock 17/22/31 Gen 3 slides, barrels, and upper parts kits. Ensure your slide is compatible with Gen 3 specifications.
