Why This Polymer80 Kit Makes Sense for Your Bench
I’ve handled a lot of 80% frames over the years, from folks bringing them into the shop to show off their work to helping customers troubleshoot their first build. The PF940v2 isn’t just another piece of plastic. It’s engineered for the recreational builder who values a process that’s as straightforward as the end result is dependable. Think of it like a high-quality hunting rifle stock that needs final inletting—you’re doing the final fitting, but the critical geometry is already there, locked in. For the concealed carry lifestyle enthusiast who wants a deeply personal sidearm, or the shooter who just enjoys the mechanics, this kit removes the guesswork from the most complex part: the frame itself. The included jig is the real workhorse, guiding your drill press or hand tools to create a functional firearm that meets your specs.

How Does the Polymer80 PF940v2 Stack Up?
When you’re budgeting for a build, it’s smart to know what you’re comparing. I see a lot of folks get tempted by the super cheap options online, only to run into fitment issues that turn a fun project into a headache. Here’s a clear, side-by-side look.
| Feature | Polymer80 PF940v2™ | Budget Import Frame (~$65) | Premium Machined Aluminum Frame (~$250+) |
|---|---|---|---|
| Material | Reinforced Polymer | Basic Polymer | 7075-T6 Aluminum |
| Quality & Fit | Precision molded, consistent | Often requires significant fitting | CNC precision, exceptional fit |
| Compatibility | Designed for Gen 3 parts | Hit-or-miss with OEM parts | Typically designed for specific, often proprietary parts kits |
| Shipping | Fast, domestic | Slow, international | Varies, often domestic |
| Lifespan/Durability | Proven long-term service life | Unknown, potential for stress cracks | Extremely high, metal frame longevity |
| Price Point | Mid-range, includes jig | Very low, jig often separate/extra | High, jig rarely included |
The Polymer80 sits in a practical sweet spot. You’re not gambling on a no-name import that might not work, and you’re not diving into the deep end with a high-cost metal frame for your first build. It’s the sensible choice, like opting for a reliable mid-grade scope instead of the bargain-bin model that won’t hold zero.
The Straight Talk: Pros and Cons
After handling these and talking to hundreds of builders, here’s my honest take.
What works well:
- ✅ Complete Kit: The jig is included and it’s quality steel. You aren’t hunting for a separate, compatible jig.
- ✅ Proven Design: The PF940v2 platform has a long track record. The ergonomics and geometry are tried and true.
- ✅ Good Instructions: Polymer80 provides clear, step-by-step guides that make the process accessible for a first-timer.
- ✅ Wide Parts Compatibility: Uses readily available Gen 3 Glock components, slides, and barrels, giving you endless customization.
- ✅ Sturdy Construction: The polymer is reinforced in high-stress areas. It doesn’t feel cheap or flimsy.
What you should know:
- ❌ Requires Tools & Skill: This is not a drop-in part. You need a drill press, hand router, or quality Dremel skills and patience. If that sounds like more than you want, see our complete pistols for ready-to-shoot options.
- ❌ Polymer Feel: Some shooters simply prefer the heft and solidity of a metal frame. If that’s you, this won’t convert you.
- ❌ Final Finishing: You’ll need to do some sanding and smoothing after milling for a professional look. It’s part of the build, but it’s extra work.
Who Should (and Shouldn’t) Buy This Kit
Buy the Polymer80 PF940v2™ kit if:
- You’re a hands-on hobbyist who enjoys building and customizing.
- You want a full-size 9mm platform for competition, home defense, or the range.
- You understand the legal requirements for manufacturing a firearm for personal use.
- You have access to basic workshop tools (drill press, vise, files/sandpaper).
- You value the customization of a built-from-parts firearm over an off-the-shelf model.
Skip the Polymer80 PF940v2™ kit if:
- You want a firearm ready to shoot out of the box. (Check our handgun selection instead).
- You’re uncomfortable with power tools or lack the workspace for a project.
- Your primary goal is the absolute lowest cost; the required tools add to the total investment.
- You are unsure about the federal and state laws regarding 80% frames. Always know your local regulations.
Common Concerns, Answered
“Is this legal for me to buy and build?”
Under federal law, purchasing an 80% frame for personal use (not for resale) is generally legal. However, you must be legally eligible to possess a firearm. State and local laws vary dramatically. It is your responsibility to know and comply with the laws in your city, county, and state before purchasing. We ship only to locations where it is compliant to do so.
“How difficult is the build process?”
With the right tools and patience, a mechanically inclined person can complete it in an afternoon. The jig does the alignment for you. The most common issue is rushing the milling or drilling steps. Go slow, follow the instructions, and test-fit parts often. There are countless video tutorials that walk through every step.
Frequently Asked Questions
Where can I buy a Polymer80 PF940v2 kit online?
You can purchase the Polymer80 PF940v2™ 80% Full Size Frame and Jig Kit right here at Imbertsmithersarms (imbertsmithersarms.com). We ship quickly and discreetly from Grand Forks, ND.
What tools do I absolutely need to complete this frame?
At a minimum, you’ll need a handheld power drill or drill press, a vise to securely hold the jig, and a rotary tool (like a Dremel) with router bits or end mills to clear the recoil spring channel and trigger housing pocket. Quality drill bits and files/sandpaper for finishing are also essential.
Will Gen 4 or Gen 5 Glock parts work with this frame?
No, the PF940v2 is designed specifically for Generation 3 Glock components. Gen 4 and Gen 5 parts have different recoil spring assemblies and locking block designs that are not compatible. Stick with Gen 3 slides, barrels, and internal parts kits for a smooth build.
Does the finished frame have a serial number?
No, the frame is unfinished and does not come with a serial number. Federal law allows you to manufacture a firearm for personal use without serializing it. However, some states have enacted laws requiring serialization. You must check and comply with all applicable laws in your jurisdiction.
How does the grip texture and ergonomics compare to a factory Glock?
The Polymer80 frame has a more aggressive stippling pattern than a standard Glock, which most shooters find provides a better grip. The ergonomics are also different, with a straighter grip angle that many compare to a 1911, which can feel more natural for some shooters.
Is the jig reusable?
The steel jig is durable and can typically be used for multiple builds if cared for. However, the drill guide holes can become slightly wallowed out with repeated use, potentially affecting precision on subsequent frames. For best results on every build, using a fresh jig is recommended.
What is your return policy on an 80% frame kit?
Due to the nature of the product, we cannot accept returns on 80% frames or jigs that have been drilled, milled, or otherwise altered. Unaltered kits in original packaging can be returned within 30 days. Please see our full return policy for details.
