Why This Polymer80 PF940 Kit Stands Out
After over a decade in this business, I’ve seen a lot of 80% frames come and go. What keeps shooters coming back to the Polymer80 PF940 platform isn’t just hype—it’s a track record. This isn’t a novelty item; it’s a serious piece of kit for someone who wants a handgun that fits their hand and their needs perfectly. The jig is precise, the polymer frame has the right flex and feel, and when paired with quality parts, you end up with a pistol that runs as hard as you do, whether that’s on the range, in a training class, or as part of your concealed carry lifestyle. For the budget-conscious builder who doesn’t want to cut corners, this kit hits a sweet spot.

The Good and The Honest Truth
What You’ll Like:
- ✅ Proven Platform: Based on the widely supported Gen 3 Glock® design, so parts, holsters, and mags are everywhere.
- ✅ Complete Kit: Comes with the precise jig, drill bits, and frame. You supply the tools and the elbow grease.
- ✅ Customization Ready: The 80% frame is a blank canvas for stippling, undercuts, and color fills to make it truly yours.
- ✅ Balanced Feel: The polymer construction and ergonomics offer a different, often more comfortable, grip angle than a stock frame.
- ✅ Build Satisfaction: There’s a real pride in running a pistol you assembled and finished yourself.
Things to Consider:
- ❌ Requires Work & Tools: This is not a drop-in part. You need a drill press, hand drill, or router, and some shop skills. If that’s not your thing, check out our stripped frames for a simpler route.
- ❌ Polymer is Polymer: While it’s tough, it won’t have the heft or “machined” feel of a metal frame. For that experience, look at our metal 80% frames.
- ❌ Initial Investment: The kit price is just the start. You’ll need a parts kit, slide, and barrel to complete the build.
Who This Kit Is For (And Who Should Pass)
Buy it if: You’re a hands-on shooter who enjoys the building process as much as the shooting. You want a personalized duty-grade or concealed carry pistol and understand the 80% process. You value the flexibility of the aftermarket Gen 3 ecosystem. You’re looking for a project that teaches you exactly how your firearm functions.
Skip it if: You need a complete, ready-to-shoot pistol right now. You don’t have access to basic workshop tools (drill, vise, files). You’re looking for the absolute lightest or heaviest possible frame. You prefer the out-of-the-box warranty and support of a factory firearm. For those needs, our complete handguns are a better fit.
Common Questions & Concerns
“Is this legal for me to build?”
This is an 80% frame, not a firearm. In most states, it is legal for a non-prohibited person to manufacture a firearm for personal use without serialization. However, laws vary by state and locality. It is your responsibility to know and comply with all federal, state, and local laws before purchasing or manufacturing.
“How difficult is the build?”
With patience and the right tools, it’s a manageable weekend project for someone with basic mechanical aptitude. The jig does most of the guiding. The most common hiccup is rushing the drilling or milling steps—take your time.
“What tools do I absolutely need?”
At a minimum: a sturdy vise, a hand drill or drill press, a set of quality drill bits (included bits work, but good ones are better), and a rotary tool (like a Dremel) with milling bits for removing the polymer tabs. Safety glasses are non-negotiable.
Frequently Asked Questions
What’s included in the Polymer80 PF940v2™ and PF940Cv1™ 80% Frame and Jig Kit Bu…?
The kit includes one 80% polymer frame (you choose the model), the corresponding multi-piece steel and polymer jig, the necessary drill bits for the pin holes, and the rear rail module. It does not include a parts kit, slide, barrel, or magazine.
What’s the difference between the PF940v2 and the PF940Cv1?
The PF940v2 is a full-size frame compatible with Gen 3 Glock 17/22/31 slides and parts. The PF940Cv1 is a compact frame compatible with Gen 3 Glock 19/23/32 slides and parts. Your choice depends on whether you want a full-size or compact/concealed carry platform.
Do I need any special skills to complete this 80% frame?
You need basic mechanical skills, patience, and the ability to follow instructions carefully. Experience with basic power tools (drill, rotary tool) is highly recommended. If you’ve ever assembled furniture from a box or done minor home repairs, you have the foundational skills.
Will this work with aftermarket slides and barrels?
Yes, that’s one of the major benefits. Because it’s designed around the Gen 3 Glock specification, it is compatible with the vast universe of aftermarket slides, barrels, triggers, and accessories made for that platform.
Where can I buy a Polymer80 PF940v2™ and PF940Cv1™ 80% Frame and Jig Kit Bu… online?
You can purchase it right here at Imbertsmithersarms (imbertsmithersarms.com). We ship same-day from Grand Forks, ND, with discreet packaging.
Is the jig reusable?
The jig is designed for multiple uses, though the drill bushings can wear over time. For most builders completing a single frame, the jig will hold its precision just fine.
What parts do I need to buy separately to complete the pistol?
You will need a Lower Parts Kit (LPK), a slide completion kit (firing pin, extractor, etc.), a slide, a barrel, and sights. We carry all these components—browse our Glock parts section to find what you need.

Been in the market for a while and finally decided to buy from Imbertsmithersarms. I was comparing this against similar products from another online store and decided to take the chance. Glad I did. Arrived in 5 days, well-packaged, and the quality speaks for itself. Installed it on my G19 Gen5 and ran 101 rounds through it without a single hiccup. This is the real deal.
