Polymer80 PF940C 80% Pistol Frame – 3-Pack

If you are a builder who values efficiency without cutting corners, the polymer80 pf940c 80% pistol frame – 3-pack offers a smart way to stock up on one of the most reliable platforms for custom pistol projects. Each frame in this bundle is the same PF940C Compact variant favored by DIY enthusiasts for its compatibility with Gen 3 Glock 19 internals and holsters. Whether you are planning multiple builds or want spares on hand, this pack delivers consistent quality and a straightforward machining process.

Overview

The polymer80 pf940c 80% pistol frame – 3-pack is a bulk option for builders who want to complete several frames at once. Each frame is precision-molded from reinforced polymer and requires finishing of the fire control pocket, trigger housing pocket, and pin holes. The compact frame is designed to accept standard Glock 19 slide assemblies, barrels, and lower parts kits, making it a versatile base for both range guns and concealed carry projects. With no serial number on the frame, it is your responsibility to ensure compliance with all local, state, and federal laws before beginning work.

Features & Specs

Each frame in the polymer80 pf940c 80% pistol frame – 3-pack shares the same specifications as the single unit, but bundled for better value. Here is what you get per frame:

• Compact grip angle with a 1911-style undercut trigger guard for improved ergonomics
• Integrated rail system (Picatinny standard) for mounting lights or lasers
• Reinforced polymer construction with stainless steel rear rail module and locking block

Additional specs include compatibility with Gen 3 Glock 19 slides, barrels, and lower parts kits. The frame material is a glass-filled nylon polymer that resists impact and chemical exposure. Each kit includes the frame, rail module, locking block, and necessary pins. You will need to complete the jig work using a router, drill press, or hand tools.

• Manufacturer: Polymer80
• Category: Frames
• Frame size: Compact (fits Glock 19 slides)

The 3-pack format means you can finish one frame immediately and save the others for future builds, or work on all three simultaneously to maintain consistent tolerances. The polymer80 pf940c 80% pistol frame – 3-pack is a practical choice for anyone who regularly builds or modifies pistols.

Who It’s For

This bundle is intended for experienced builders who understand the legal and mechanical requirements of completing an 80% frame. If you have already finished a single PF940C and want to streamline your next projects, the 3-pack reduces per-unit cost and minimizes ordering hassle. It is also a good fit for small groups of builders who want to split the purchase. Because each frame is unmarked and requires finishing, you must confirm that you are legally allowed to manufacture a firearm for personal use in your jurisdiction. This product is not for first-time builders who lack access to proper tooling or knowledge of safe firearm construction.

Shipping & FFL

Since the polymer80 pf940c 80% pistol frame – 3-pack is not a serialized firearm, it ships directly to your doorstep without needing a transfer through a Federal Firearms License (FFL) holder. However, once you complete the frame, you are required by law to ensure it is not transferable to others unless you hold a manufacturer’s license. We recommend checking your state and local laws regarding unfinished frames before ordering. Some jurisdictions restrict or prohibit ownership of 80% frames. By purchasing, you confirm you are of legal age and not prohibited from possessing firearms. We ship via UPS Ground with adult signature required.
