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

Overview

The Polymer80 PF940Cv1™ 80% Compact Frame and Jig Kit (Glock® 19/23 Compatible) – 3-Pack delivers three complete frame kits for builders requiring multiple lower receivers for serialized or custom builds. Each kit includes the PF940Cv1™ 80% polymer frame, a jig, drill bits, and all necessary hardware. The frames are compatible with Gen 1 through Gen 4 Glock® 19 and 23 slide assemblies, barrels, and lower parts kits. The 80% frame requires finishing with standard tools and a drill press or hand drill to complete the fire control pocket and pin holes. This 3-pack is optimized for high-volume builds, training platforms, or inventory stock for an FFL-holding gunsmith.

Each frame in this polymer80 pf940cv1™ 80% compact frame and jig kit (glock® 19/23 compatible) – 3-pack is molded from impact-resistant, glass-reinforced nylon polymer. The integral jig system indexes precisely to the frame to ensure correct hole alignment. The kit includes three jigs, three frames, three sets of drill bits, and three locking block rails. The frame geometry replicates the Glock® 19/23 compact grip angle with a textured front strap, rear strap, and side panels.

Who It Is For

This polymer80 pf940cv1™ 80% compact frame and jig kit (glock® 19/23 compatible) – 3-pack is intended for licensed gunsmiths, FFL holders, and experienced hobbyists who need multiple frames for batch builds, custom projects, or training inventory. It is not a complete firearm and requires finishing with tools. The 3-pack reduces per-unit cost and ensures identical frame characteristics across builds. It is suitable for those familiar with 80% frame finishing procedures, including drilling, milling, and fitting of lower parts. The kit is not recommended for first-time builders due to the precision required for fire control pocket milling.

Each frame in the polymer80 pf940cv1™ 80% compact frame and jig kit (glock® 19/23 compatible) – 3-pack is designed for users who want to build a Glock® 19/23 compact pattern pistol without purchasing complete OEM frames. The 80% status means no serial number is required until the frame is completed and transferred to a buyer. For commercial sales, the completed frame must be serialized and transferred through an FFL. This kit is also appropriate for training organizations building multiple identical firearms for armorer courses.

Shipping & FFL

This polymer80 pf940cv1™ 80% compact frame and jig kit (glock® 19/23 compatible) – 3-pack ships directly to your shipping address. Because these are unfinished 80% frames, they are not classified as firearms under federal law and do not require transfer through a Federal Firearms License (FFL) for purchase or shipment. However, you must comply with all applicable state and local laws regarding the possession and finishing of 80% frames. Some states and localities restrict or prohibit the ownership of unfinished frames or require serialization upon completion. It is your responsibility to verify legality in your jurisdiction before ordering. If you complete the frame into a functional firearm, federal law requires that it be serialized if you intend to sell or transfer it. We recommend consulting an attorney or your local ATF field office for guidance. No returns are accepted on opened kits due to the nature of the product and jig wear. All sales are final.
