Features & Specs

Each frame in this Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 compatible) – 3-pack is precision-molded from high-strength polymer. The kit includes the jig, drill bits, and necessary pins to get started. Here is what you can expect from each frame:

• Compact size built for Glock 19/23 holster compatibility and magazine interchangeability
• Textured grip panels and an integrated beavertail for improved control during rapid fire
• Factory-compatible trigger housing and locking block channels that require minor finishing work

The jig system simplifies the process of milling the three pin holes and the rear rail channel. Each kit comes with clear instructions, though you will still need basic hand tools like a drill press or a hand drill. The frames are made from a durable, impact-resistant polymer that holds up well under standard use. As with any 80% build, you are responsible for completing the frame to a functional state.

Who It’s For

This 3-pack is ideal for builders who want multiple projects lined up without ordering individual kits. If you are a gunsmith looking to offer custom compact builds, or a hobbyist who enjoys experimenting with different slide and barrel combinations, this Polymer80 PF940Cv1 80% Compact Frame and Jig Kit (Glock 19/23 compatible) – 3-pack gives you three identical starting points. It also works well for group builds or as a shared project among friends. Because the frames are unfinished, they require your attention and effort to complete, which is part of the appeal for those who appreciate hands-on work.
