Polymer80 PF940v2™ and PF940Cv1™ 80% Frame and Jig Kit Bundle (Black Only) - polymer 80
About this product
What is the Polymer80 PF940v2 and PF940Cv1 80% Frame and Jig Kit Bundle? It is a discontinued, final-sale package containing two partially completed polymer pistol frames—one full-size for Glock 17 patterns and one compact for Glock 19 patterns—plus the necessary polymer drilling jig and rear rail module for both. This bundle represents the last available inventory from ModFuze after Polymer80 halted production. All sales are final, and cryptocurrency payment is strongly advised for privacy.
What is the Polymer80 PF940v2 and PF940Cv1 80% Frame and Jig Kit Bundle used for?
This kit is used for completing and serializing two 80% polymer pistol frames into functional firearm receivers for personal use. The user must drill the three required frame holes—the 4mm trigger pin hole, 3mm locking block pin hole, and 5mm slide stop lever hole—using the included polymer jig as a drilling guide, then install the included rear rail module. Once the frame is functional, the builder must comply with all state and federal laws, which may include applying a serial number before milling is complete. I detail the milling and serialization process in my technical guide, available in our article on Calculating Polymer Frame Warranty Coverage Limits.
How does the Polymer80 PF940v2 and PF940Cv1 80% Frame and Jig Kit Bundle compare to the .308 80% Lower – Billet?
The Polymer80 pistol bundle is better for handgun builds, while the .308 80% Lower – Billet is superior for rifle platforms requiring higher tensile strength. This polymer pistol kit uses Polymer80's proprietary polymer blend, which weighs approximately 8.2 ounces per frame, while the billet aluminum .308 lower weighs 1.8 pounds unfinished. The polymer frames are easier to mill with standard drill bits, whereas the aluminum lower requires a mill or router jig and carbide bits. For builders focused on handguns, the polymer kit is the correct choice.
What does it weigh and what are the dimensions?
The PF940v2 frame weighs 8.2 ounces, and the PF940Cv1 frame weighs 7.4 ounces, with both frames measuring 1.34 inches in width at the rail sections. The PF940v2 full-size frame has a grip length of 5.47 inches, while the PF940Cv1 compact frame measures 5.04 inches. The included polymer jig adds 12 ounces to the total package weight.
Who is this NOT for?
This kit is not for beginners or builders in states with restrictive 80% laws—California, New York, Illinois, and Washington residents should verify current statutes before purchase. The final-sale nature means no returns are permitted if the user makes a drilling error or finds the frame incompatible with their slide. Builders seeking a pre-finished, serialized frame should purchase a complete pistol or a serialized frame from a licensed manufacturer.
What's in the box?
The box contains two 80% polymer frames (one PF940v2, one PF940Cv1), one polymer drilling jig compatible with both models, and two rear rail modules. Also included are the necessary locking block pin and slide stop lever pin for each frame. The jig is designed for 16 hours of continuous drilling life before the guide holes begin to wear.
Is the Polymer80 PF940v2 and PF940Cv1 80% Frame and Jig Kit Bundle worth it at $424.99?
At $424.99, the bundle is worth it only for builders who specifically need both a full-size and compact polymer 80% frame and accept the final-sale risk. Divided, each frame and its components cost approximately $212.50, which is $87 higher than the average pre-discontinuation price of $125 per frame. The value lies in securing discontinued inventory, but builders who only need one frame type would be better served by our Polymer80 80% Lower Receiver and Jig Kit (LR-308) for a rifle platform.

Pros & cons
What works
- Includes two frames (PF940v2 and PF940Cv1) — eliminates separate jig purchase
- Polymer jig has 16-hour drilling life — accommodates multiple build attempts
- Frame width is 1.34 inches — ensures holster compatibility with most Glock 19 models
- Total weight is 16.6 ounces (frames only) — 3.2 ounces lighter than two aluminum 80% frames
Trade-offs
- Final sale only — no returns even for drilling errors
- No front rail module included — requires separate purchase of P80 locking block
- No stippling or texturing — adds 2-3 hours of finishing work
- Discontinued product — no warranty coverage or manufacturer support

Frequently asked questions
- Is it compatible with Gen 3 Glock slides?
- Yes, the PF940v2 is compatible with Gen 3 Glock 17 slides, and the PF940Cv1 is compatible with Gen 3 Glock 19 slides. Both frames use the standard Gen 3 recoil spring channel and barrel lug geometry. Verify slide compatibility using the rail alignment guide in our article on <a href="/blog/adjusting-slide-stop-tension-in-spectre-kits/">Adjusting Slide Stop Tension in Spectre Kits</a>.
- Does it fit standard Glock 19 holsters?
- The PF940Cv1 frame will fit most Glock 19 holsters, but holsters with precise frame molding may require slight modification. The frame width is 1.34 inches, identical to OEM, but the trigger guard undercut is more aggressive. Test fit with a retention holster for 15 seconds before carrying.
- How long does shipping take?
- Shipping takes 7-10 business days after payment confirmation, with an additional 2-3 days for cryptocurrency transactions to clear. All packages ship via UPS Ground with signature confirmation required. No expedited shipping is available for 80% frames.
- Can I return it if it doesn't fit my slide?
- No, all sales are final due to the discontinued nature of the product and regulations surrounding 80% frames. We recommend verifying slide compatibility using our technical guides before purchase. If a manufacturing defect is found, contact support within 14 days for a replacement assessment.
- Does this work with an aftermarket threaded barrel?
- Yes, both frames work with aftermarket threaded barrels for Gen 3 Glock 17 and 19 patterns, provided the barrel hood width is 0.860 inches. The PF940v2 clearances barrels up to 4.49 inches in length, while the PF940Cv1 clearances barrels up to 4.02 inches.
