Polymer80 PF940V2 80% Pistol Frame Only

For builders seeking a blank canvas without the burden of a serialized receiver, the Polymer80 PF940V2 80% Pistol Frame Only offers a precision-machined platform designed for complete customization. This uncompleted frame requires finishing and assembly, giving the builder full control over trigger components, slide configuration, and ergonomic fit. Machined from high-strength, impact-resistant polymer, the PF940V2 replicates the geometry of a standard compact frame while providing the structural rigidity necessary for reliable cycling and long-term durability. Each frame includes integrated front and rear slide rails, a steel locking block, and a MIL-SPEC trigger housing pin hole pattern, ensuring compatibility with a wide range of Gen3-style aftermarket parts.

Overview

The Polymer80 PF940V2 80% Pistol Frame Only represents a milestone in the DIY firearm community, offering a legally unregulated frame blank that requires machining of the fire control pocket and trigger housing shelf before assembly. This specific frame is designed for Glock Gen3-compatible small frames, accepting standard 9mm, .40 S&W, and .357 SIG slide and barrel assemblies. The frame features aggressive front and rear slide serrations, an integrated beavertail, and a textured grip pattern for positive purchase under recoil. As a true 80% frame, it does not constitute a firearm under federal regulation until the fire control pocket is fully machined and the frame is completed by the end user. The PF940V2 is the workhorse of the Polymer80 lineup, valued for its dimensional accuracy and robust polymer composition that resists flex during high-round-count use.

Who It’s For

The Polymer80 PF940V2 80% Pistol Frame Only is intended for experienced builders who possess the necessary tools and knowledge to complete a firearm frame from an 80% blank. This product is ideal for gunsmiths, hobbyists, and shooters who want a fully customized pistol without the restrictions of a factory serialized receiver. It is also suited for those building a dedicated competition, training, or backup firearm with specific trigger and slide preferences. Novice builders should first research the machining process, required tooling (including a drill press, end mills, and jig), and local, state, and federal laws regarding 80% frame completion. This frame is not for casual assembly; it demands mechanical aptitude and strict adherence to legal guidelines.

Shipping & FFL

Because the Polymer80 PF940V2 80% Pistol Frame Only is classified as a non-firearm frame blank (not a serialized receiver), it does not require transfer through a Federal Firearms License (FFL) dealer for shipment within the United States. However, it is the sole responsibility of the purchaser to verify that ownership, possession, and completion of an 80% frame are legal in their specific state, county, and municipality. Some states and localities restrict or prohibit the possession or manufacture of unserialized frames. By purchasing this product, you acknowledge that you are compliant with all applicable laws. We ship via UPS Ground or USPS Priority Mail to the address on file; no signature is required unless the package value exceeds $500. International shipping is not available. No returns or exchanges are accepted on 80% frames due to legal restrictions. If your jurisdiction requires an FFL for frame blanks, please contact us prior to ordering to arrange compliance. This product may not be shipped to P.O. boxes in certain states. All sales are final.
