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 seeking consistent, repeatable results. Each kit includes the unfinished PF940Cv1 frame, a precision-machined jig, and all necessary drill bits and end mills required for completion. Designed for Glock 19 and 23 generation 3 pattern slides and parts, this 3-pack provides the foundation for three separate builds from a single purchase. The frames are manufactured from reinforced polymer with molded-in steel trigger housing rails and front locking block rails, reducing the need for additional aftermarket components during assembly.

Features & Specs

Each frame in the polymer80 pf940cv1 80% compact frame and jig kit (glock 19/23 compatible) – 3-pack is fabricated from a proprietary high-impact polymer compound that resists flex under recoil. The jig system indexes the frame in three axes to ensure correct hole placement during drilling. The kit includes hardened steel drill bits and a carbide end mill for the pin holes and trigger channel. All three frames share identical geometry, allowing batch completion with a single setup.

Who It’s For

The polymer80 pf940cv1 80% compact frame and jig kit (glock 19/23 compatible) – 3-pack is intended for intermediate to advanced firearm builders who have experience with polymer frame finishing operations. It suits individuals who require multiple frame builds for training, spare parts inventory, or consistent platform duplication. Builders should possess a drill press or hand drill with a depth stop, a vise for securing the jig assembly, and a set of deburring tools for final frame finishing. This product is not recommended for first-time builders without prior experience in 80% frame completion. The 3-pack format reduces per-unit cost compared to single-frame purchases and ensures all frames are from the same production batch for dimensional consistency.
