Features & Specs

The Polymer80 PF940Cv1™ 80% Compact Frame and Jig Kit (Glock® 19/23 Compatible) is built for those who value precision and durability. The frame itself is constructed from high-strength, impact-resistant polymer, designed to withstand the rigors of regular range use. It is compatible with Glock 19 and 23 gen 3 parts, giving you a wide range of aftermarket options. The integrated jig system ensures your drill holes align perfectly, reducing the margin for error. Here is a breakdown of what you get:

• 80% compact frame with a standard rail system for mounting lights and lasers
• Includes all necessary jig, drill bits, and end mill for frame completion
• Textured grip panels and an ergonomic undercut trigger guard for improved control

Beyond the basics, this kit features a full-length Picatinny rail on the dust cover, which is a major upgrade over the factory Glock setup. The frame also has an aggressive front and backstrap texture, so your grip stays locked in even with sweaty hands or in wet conditions. The magazine release is reversible for left-handed shooters, and the trigger guard is designed to work with gloved hands. When you finish the Polymer80 PF940Cv1™ 80% Compact Frame and Jig Kit (Glock® 19/23 Compatible), you end up with a frame that feels custom-fit to your hand.

Who It’s For

This kit is ideal for the DIY enthusiast who wants to build a reliable compact pistol without needing a full machine shop. It is perfect for shooters who want a Glock 19 or 23 compatible frame with an integrated rail, something the factory models lack. The Polymer80 PF940Cv1™ 80% Compact Frame and Jig Kit (Glock® 19/23 Compatible) also appeals to those who enjoy personalizing their firearm—you can choose your own slide, barrel, trigger, and sights. If you have basic mechanical skills and a few hours of patience, you can complete this build at your kitchen table. It is a great weekend project that results in a fully functional, custom firearm.

• Home builders and gunsmithing hobbyists looking for a challenging but achievable project
• Concealed carriers who want a compact frame with rail options and improved ergonomics
• Competition shooters who prefer a custom trigger and grip angle over factory offerings
