Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible)

If you are looking to build a true concealed carry pistol from the ground up, the Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible) is a solid starting point. This kit gives you the backbone of a compact handgun without the serialized frame, putting the build process directly in your hands. Whether you are a weekend tinkerer or a seasoned builder, this frame is designed to accept Glock 26 and 27 parts with minimal fuss.

Overview

The Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible) is a complete DIY solution for anyone wanting a custom subcompact pistol. The frame itself is made from a rugged, glass-reinforced polymer that mirrors the dimensions of the factory Glock 26 frame but adds a few ergonomic improvements. The kit includes the 80% frame, a drill and pin jig, and all necessary bits to complete the frame. Because it is an 80% lower, you are finishing a non-firearm component, which means no serial number and no transfer paperwork until you complete it. This kit is a clean, straightforward path to a functional subcompact build.

Features & Specs

When you open the box, you will find everything you need to finish the frame at home. The kit simplifies the process, so you can focus on the fit and finish rather than hunting for parts. Here is what comes with the Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible):

• Complete 80% subcompact frame with integrated trigger guard undercut and a more vertical grip angle for improved pointability.
• Precision-machined jig with hardened steel drill guides that align perfectly with the frame’s pin holes.
• Three drill bits, a carbide end mill, and all necessary pins and rails to complete the frame assembly.

The frame itself is built to accept standard Glock 26 and 27 slide assemblies, barrels, and lower parts kits. The polymer is textured with a subtle stippling pattern that provides a secure grip without being abrasive. The rail system is a proven, drop-in design that reduces slop and improves accuracy over earlier 80% frames. You are getting a platform that is both durable and easy to work on.

• Compatible with Glock 26, 27, and 33 slide and barrel configurations (9mm, .40 S&W, and .357 SIG).
• Includes a locking block and rear rail module pre-installed in the jig for hassle-free alignment.
• Frame material is a high-impact, chemical-resistant polymer that withstands heavy use and cleaning solvents.

Who It Is For

This kit is for the hands-on builder who values control over every component in their carry gun. If you are comfortable with basic hand tools and have a drill press or a steady hand with a hand drill, you can finish this frame in a couple of hours. It is ideal for someone who wants a subcompact firearm that fits their hand better than a stock Glock 26, because the Polymer80 PF940SC 80% Subcompact Frame and Jig Kit (Glock 26/27 Compatible) allows you to customize the trigger pull, sights, and grip texture from the start. It is also a practical choice for those in states where 80% frames are legal and no FFL transfer is required for the unfinished component. This is not a drop-in project for beginners, but if you have built an AR-15 lower or assembled a Glock slide, you will be right at home.

• Best for intermediate to advanced home builders who want a deep-carry pistol.
• Suitable for shooters who prefer the compact grip of a Glock 26 but want a more aggressive texture and improved ergonomics.
• Not recommended for first-time 80% builders without prior experience with pin alignment and rail fitting.

Shipping & FFL

You do not need a background check to purchase this item. However, once you complete the frame by drilling the required holes and removing the remaining material, you are legally responsible for ensuring the finished firearm complies with all local, state, and federal laws. We recommend verifying your state and local regulations regarding 80% builds before ordering. Some states and municipalities have restrictions on unserialized firearms, and it is your duty to stay compliant. We ship this kit via standard carriers and include tracking information. No signature is required for delivery.
