Polymer80 PF940v2™ 80% Full Size Frame and Jig Kit (Glock® 17/22/24/31/34/35 Compatible) - 3-Pack - polymer 80
Pros & cons
What works
- CNC-machined aluminum jig ensures ±0.2 mm hole alignment accuracy across all three frames.
- Rail module design reduces front rail cant issues common in early P80 models by 80%.
- Three-frame bulk kit provides a consistent matching platform for multiple caliber or stippling projects.
Trade-offs
- No stippling pre-installed — adds $40-80 finishing step for texture or custom grip work.
- Trigger guard undercut requires aggressive manual filing (approx. 15 mins per frame) for optimal high-hand grip.
- Jig assembly uses set screws prone to cross-threading if over-torqued beyond 15 in-lbs.

About this product
The Polymer80 PF940v2™ 80% Full Size Frame and Jig Kit is a 3-pack of unfinished polymer frames requiring user completion to build custom Glock-compatible handguns. This kit includes all dedicated jigs and hardware for three complete large-frame builds. It is sold as a non-firearm component until serialization and finishing steps are performed by the end user.
What is the Polymer80 PF940v2 3-Pack used for?
This kit provides the foundational starting point for constructing three custom large-frame Glock-style pistols from an 80% complete state. The user must drill the requisite trigger pin holes (typically 3mm and 4mm) and remove polymer tabs from the fire control pocket using the included jig, which typically requires 45-90 minutes per frame for a prepared user. After finishing, the frame accepts standard aftermarket Glock slide components, frames, and lower parts kits compatible with the PF940v2 design.
How does the PF940v2 compare to the ModFuze .308 80% Lower – Billet?
The PF940v2 kit is optimized for handgun platforms, whereas the .308 80% Lower – Billet supports rifle platforms like the LR-308. The polymer pistol frame weighs approximately 250 grams unfinished, making it 65% lighter than the aluminum billet rifle lower, but it offers less inherent rigidity for suppressing attachments compared to the machined alternative. The Jig system for the PF940v2 is also specific to its 5-hole drilling pattern, not interchangeable with rifle fixtures.
What does it weigh and what are the dimensions?
Each unfinished PF940v2 frame weighs approximately 250 grams (8.8 oz), and the complete kit for three frames, including three jigs and hardware, ships in a 300 mm x 200 mm x 150 mm box weighing 2.1 kg. The finished frame dimensions are identical to a standard Glock 17 frame, with a length of 185 mm, a height of 122 mm, and a width of 28 mm at the slide rails.
Who is this NOT for?
This product is not for individuals seeking a serialized, ready-to-assemble frame or those in jurisdictions prohibiting unserialized firearm components. It requires access to a drill press, hand tools, and finishing supplies outlined in Best Drill Bits for Polymer Frame Modifications. The user must also be willing to assume liability for compliance with all federal, state, and local laws regarding manufacture, serialization, and registration.
What's in the box?
The kit includes three 80% complete Polymer80 PF940v2 frames in dark gray polymer, three dedicated CNC-machined aluminum jigs with locking clamps, three sets of frame rail modules for front and rear positioning, and six drill bits (3mm and 4mm sizes for pin holes). No springs, pins, slide parts, or tools beyond the provided drill bits are supplied.
Is the PF940v2 3-Pack worth it at $610.99?
At approximately $203.66 per frame inclusive of jig, this cost is competitive for bulk procurement but represents a 15% premium per unit over purchasing individual kits during standard production. The value is for builders requiring multiple frames for different configurations, as the dedicated jig ensures repeatable accuracy across all three units. For a single build, an individual kit or a pre-serialized frame from an alternate source may be more cost-effective when factoring in finishing labor.

Frequently asked questions
- Is it compatible with Glock 19 slides?
- No, this PF940v2 'Full Size' frame is compatible only with large-frame Glock slides and components for models 17, 22, 24, 31, 34, and 35, which share a 185 mm length. A Glock 19 slide, designed for a 174 mm compact frame, will not mate properly with this receiver.
- Can I return it if it doesn't fit?
- No, ModFuze does not accept returns on 80% frames once shipping confirmation is issued, as per company policy. We advise verifying technical specifications and local laws before purchase. Customers are responsible for ensuring compatibility with their chosen aftermarket parts kit.
- Does this work with Gen 4 or Gen 5 Glock parts?
- It is designed primarily for Gen 3 Glock component compatibility, including slide stop levers, trigger housings, and locking blocks. Most Gen 4 and Gen 5 parts, like dual-captive recoil spring assemblies, are not compatible with the PF940v2's frame geometry and will require modification.
- How long does shipping take?
- ModFuze processes and ships orders within 3 business days of cleared payment using discreet packaging. Standard shipping to Continental US addresses typically requires 5-7 business days transit time from dispatch; expedited options are not available for this product category.
