Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack

Overview

If you are building from the ground up or stocking up for future projects, the Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack delivers three complete builds worth of quality polymer frames and the tooling you need to finish them. Each kit includes the iconic compact frame that accepts Gen 3 Glock 19 or 23 parts, plus the patented jig system that keeps your drilling and routing precise. Whether you are a first-time builder or a seasoned gunsmith, this three-pack offers serious value without sacrificing the hands-on experience that makes 80% builds rewarding.

Every frame in this Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack is molded from high-strength, impact-resistant polymer and features the aggressive front and rear serrations you expect from a duty-ready frame. The integrated locking block rail system is already installed, so you skip the most tedious alignment step and jump straight to drilling the pin holes and removing the trigger housing pocket. Each kit comes with its own jig, drill bits, and end mill, so you can work on all three frames sequentially or hand them off to friends.

Features & Specs

• Compatible with all Gen 3 Glock 19 and Glock 23 OEM and aftermarket parts (slide, barrel, lower parts kit, magazine).
• Includes three unfinished PF940Cv1 frames, three reusable jigs, three sets of drill bits, three end mills, and three sets of pin installation tools.
• Frame material: reinforced polymer with textured grip panels, undercut trigger guard, and accessory rail for lights or lasers.

The jig system in this kit uses hardened steel drill bushings that index perfectly to the frame’s internal geometry. You get clean, repeatable holes every time, and the jig can be disassembled and reused for future builds. The compact grip profile fits most hands well and accepts standard 15-round Glock 19 magazines as well as the 17-rounders for a full-hand grip.

Who It’s For

This 3-pack is ideal for the builder who wants to complete multiple frames in one session or share the experience with family and friends. If you already have a bin of Glock 19 or 23 parts lying around, the Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 Compatible) – 3-Pack gives you a dedicated frame for each set of internals. It also makes a smart group project for a weekend workshop, where everyone can learn the finishing process together using the same jig setup.

Experienced builders will appreciate that you can customize each frame differently – one with a stippled grip, one with a different trigger, one left-handed – all from a single kit. Because these are 80% frames, you are not buying a completed firearm; you are buying the core component that requires your hands-on work to become functional. That means you can tailor each build to your exact preferences without paying a premium for pre-assembled options.

• Perfect for builders who want three identical frames for parts bin projects.
• Great for teaching someone the finishing process with a low-stakes, repeatable setup.
• Compact size suits concealed carry, range use, or backup gun builds.
