Release: Glock-Mod Polymer80 PF940SC Jig Kit for PF940SC Frame Blanks
About this product
The Glock-Mod Polymer80 PF940SC Jig Kit is a precision tool system designed specifically for machining PF940SC frame blanks into functional firearm receivers. This CNC-machined aluminum jig provides the exact guide patterns needed to complete your compact frame build with professional results. We've shipped 633+ units directly from our Dallas facility since late 2024, maintaining a 0.6% return rate that speaks to the kit's reliability.
What is the PF940SC Jig Kit used for?
This jig kit is used to precisely drill and mill Polymer80 PF940SC frame blanks to completion. It provides the exact template for drilling the 3mm trigger pin holes and 4mm locking block pin locations with ±0.1mm tolerance. The jig ensures your frame meets Glock OEM specifications without requiring expensive shop equipment. You'll complete the machining process in approximately 45 minutes with basic tools.
How does the PF940SC Jig Kit compare to 3D printed alternatives?
The GLOCK FRT jig provides superior rigidity and precision compared to 3D printed jigs that can flex during drilling. Our CNC-machined aluminum construction maintains dimensional stability through multiple uses, while typical PLA jigs degrade after 2-3 frames. For serious builders completing multiple PF940SC projects, our jig delivers consistent results that printed alternatives cannot match.
What does it weigh and what are the dimensions?
The complete kit weighs 1.2 pounds and measures 6.5 x 4.2 x 2.1 inches in its protective case. The aluminum jig itself has a 0.5-inch wall thickness for maximum stability during machining operations. This compact size stores easily with your other gunsmithing tools while providing a substantial work surface for frame completion.
Who is this NOT for?
This jig kit is not for builders who want pre-completed frames or lack basic machining skills. You'll need a drill press or steady hand drill, 3mm and 4mm drill bits, and files to complete the frame. If you're looking for drop-in solutions, consider our Glock 43 FRT V2 Drop-In Trigger Bar Kit instead. This is for builders who understand the 80% completion process.
What's in the box?
The kit includes the main aluminum jig body, six hardened steel drill guide bushings, and a complete set of M3 and M4 hardware for assembly. You receive all necessary components to guide your frame blank through the critical drilling and milling operations. Each bushing is rated for approximately 50 drilling cycles before requiring replacement.
Is the PF940SC Jig Kit worth it at $57.62?
At $57.62, this jig kit delivers professional-grade precision at 40% less than custom machine shop services. The investment pays for itself after your second PF940SC build compared to paying for professional milling. When paired with our Glock 3.5lb Modified Cut Nub Connector, you'll achieve a complete performance build for under $100 in specialized components.

Frequently asked questions
- Is it compatible with PF940SC frame blanks only?
- Yes, this jig is specifically designed for Polymer80 PF940SC compact frame blanks only. It will not work with full-size PF940V2 or subcompact PF940SS models. The pin spacing and rail dimensions are unique to the SC pattern.
- Does it fit Gen 3 Glock 26 slides?
- The jig creates frames compatible with Gen 3 Glock 26 slides and components. The locking block and rail specifications match OEM Glock 26 dimensions within 0.005-inch tolerance for reliable function.
- How long does shipping take?
- We ship within 24 hours from our Dallas facility via USPS Priority Mail. Most continental US orders arrive in 2-3 business days. International shipments to compliant countries take 7-10 business days with proper documentation.
- Can I return it if it doesn't fit my frame?
- We accept returns within 30 days if the jig shows manufacturing defects. Cosmetic blemishes from normal use are not covered. Contact our support team with order details - we maintain a 0.6% return rate for legitimate issues.
- Does this work with standard drill bits?
- Yes, use standard 3mm and 4mm high-speed steel drill bits. We recommend carbide-tipped bits for extended jig bushing life. Avoid using dull bits that can wander and damage the guide bushings.
