About this product
What is the Glock-Mod Polymer80 PF940C Jig Kit? The Glock-Mod Polymer80 PF940C Jig Kit is a precision machining template designed specifically for completing Polymer80 PF940C frame blanks into functional firearm receivers. This tool eliminates guesswork during the milling process required to transform an 80% frame into a finished lower. With over 272 units shipped since early 2024, it represents our most reliable jig solution for compact frame builds.
What is the Glock-Mod Polymer80 PF940C Jig Kit used for?
This jig kit is engineered specifically for machining Polymer80 PF940C frame blanks into functional Glock-compatible receivers. It provides precise guide points for drilling pin holes and routing the fire control cavity with CNC-level accuracy. The jig reduces setup time by 75% compared to freehand milling and ensures proper alignment of critical components.
How does the Glock-Mod Polymer80 PF940C Jig Kit compare to Polymer80's factory jig?
Our jig delivers superior machining precision with 0.002-inch tighter tolerances than Polymer80's factory jig. The aluminum reinforcement plates prevent flex during routing operations, whereas the factory plastic jig can warp under sustained pressure. For builders requiring absolute precision, our kit produces cleaner cuts with less finishing work required.
What does it weigh and what are the dimensions?
The complete jig kit weighs 2.1 pounds and measures 8.5 x 6.25 x 3 inches when assembled. This compact footprint fits standard bench vises while providing 360-degree access to the frame blank. The aluminum guide plates add 0.5 pounds compared to all-polymer jigs but eliminate deflection during aggressive milling.
Who is this NOT for?
This jig kit isn't suitable for beginners without prior machining experience or proper safety equipment. Operators must possess basic drill press operation skills and understand firearm safety protocols. Those seeking drop-in solutions should consider our complete trigger bar kits instead of frame machining.
What's in the box?
The kit includes three anodized aluminum guide plates, eight hardened steel drill bushings, six locking screws, and one alignment tool. All components undergo magnetic particle inspection for stress fractures before packaging. The bushings are rated for 500 drilling cycles—three times the lifespan of standard carbon steel bushings.
Is the Glock-Mod Polymer80 PF940C Jig Kit worth it at $57.62?
At $57.62, this jig delivers professional-grade precision at 40% less than custom machined alternatives. It pays for itself after two frame completions compared to gunsmithing services charging $75-100 per frame. For builders planning multiple PF940C projects, this tool ensures consistent results without outsourcing machining work.

Frequently asked questions
- Is it compatible with Gen 3 Glock 19 parts?
- Yes, the jig produces frames that accept all Gen 3 Glock 19 components. The pin spacing maintains original Glock specifications within 0.003-inch tolerance. This includes compatibility with our <a href="/products/glock-mod-blem-chip-standard-semi-auto-royal-blue-6061-aluminum-flat-glock-trigger/">BLEM-CHIP aluminum triggers</a> and standard OEM parts.
- Does it fit standard drill press chucks?
- The drill bushings require ⅜-inch shank bits, which fit most benchtop drill presses. Minimum chuck capacity needed is 0.5 inches with at least 2 inches of vertical clearance. For optimal results, use a cross-slide vise with 4-inch jaw capacity to secure the jig assembly.
- How long does shipping take?
- Orders ship within 24 hours from our Dallas, TX facility via USPS Priority Mail. Continental US delivery averages 3 business days, while Alaska/Hawaii transit takes 5-7 days. International shipments require 10-14 days with proper export documentation.
- Can I return it if it doesn't fit my frame blank?
- Returns are accepted within 30 days for unused items, but jig kits require 15% restocking fee due to calibration certification costs. Ensure your frame blank is Polymer80 PF940C specific—non-P80 frames won't align properly. Contact support@glockfrt.us.com before initiating returns.
