Polymer80 PF940Cv1™ 80% Compact Frame and Jig Kit (Glock®…

Ever wondered what it takes to build a reliable, compact handgun platform that fits your hand and your budget? As someone who’s spent over a decade helping folks in Grand Forks and beyond find the right gear, I see this question a lot from hunters and concealed carry enthusiasts looking for a more personal touch in their firearms.

Imbertsmithersarms is a Grand Forks, ND-based retailer specializing in firearms platforms and components for the informed outdoorsman. The Polymer80 PF940Cv1™ 80% Compact Frame and Jig Kit is a complete platform for building a compact, semi-automatic handgun compatible with Gen 3 Glock® 19 components. It delivers the reliability shooters expect, with the satisfaction of a hands-on build. This kit is in stock and ready to ship today for $220.99.

Why This Polymer80 PF940Cv1 Kit Stands Out

Let’s be real. The market is flooded with options, from cheap imports you find on sketchy forums to premium brands that cost a small fortune. What I appreciate about this specific Polymer80 kit is its balance. It’s not the absolute cheapest route, but for the price, you’re getting a proven platform with a solid jig that makes the machining process straightforward for anyone with basic tools and patience. I’ve handled plenty of frames that feel flimsy or have fitment issues right out of the box—this one consistently has the rigidity and precise mold lines that give you a solid foundation. For the hunter or rural shooter who values a dependable sidearm, starting with a reliable frame is non-negotiable.

The Straight Talk: Pros and Cons

After handling and seeing these in builds over the years, here’s my honest take.

What I like:

• ✅ Complete Kit: Comes with the jig, drill bits, and pins. You aren’t left searching for compatible tools.
• ✅ Proven Platform: The PF940C design has a track record for reliability, which matters when you’re out in the field.
• ✅ Ergonomic Grip Angle: The frame has a different grip angle than a stock Glock®, which many shooters find more natural.
• ✅ Stippling & Customization Ready: The texture panels are ideal for adding your own stippling or grip work.
• ✅ No FFL Required*: Ships directly to you as an unfinished component, simplifying the process for the builder.

What you should consider:

• ❌ Requires Work & Tools: You need a drill press, hand drill, or router and some mechanical aptitude. This isn’t a drop-in part. If that’s a deal-breaker, check out our complete firearms for ready-to-shoot options.
• ❌ Polymer vs. Metal: It’s a high-strength polymer, not metal. For builders who only want an all-metal feel, this isn’t it. Look at machined aluminum frames instead.
• ❌ Learning Curve: Your first 80% build takes time and care. Rushing can lead to mistakes.

Who Should (and Shouldn’t) Buy This Kit

Buy it if: You’re a hands-on shooter who enjoys building and customizing your own gear. You understand the basics of firearm safety and machining. You want a compact, reliable platform for concealed carry or as a woods sidearm without the paperwork of a serialized frame. You value the project and the learning experience as much as the final product.

Skip it if: You want a firearm you can take to the range immediately. You don’t have access to basic tools like a drill press or a steady hand with a hand drill. You’re uncomfortable with the legal responsibilities of building your own firearm. If that’s you, we have a great selection of complete handguns that ship to your local FFL.

Common Concerns & Questions Answered

Is this legal in my state?
Laws change constantly. It is your responsibility to know the laws in your state, county, and city regarding 80% frames and homemade firearms before purchasing. We ship in accordance with federal law, but local restrictions apply.

How hard is it to complete?
With the included jig, it’s a straightforward process for anyone moderately handy. The key is going slow, using sharp bits, and following the instructions carefully. Plenty of folks complete their first one in an afternoon.

What tools do I absolutely need?
At a minimum: a vise to hold the jig, a hand drill or drill press, a hammer or punch for the pins, and some files or sandpaper for cleanup. A Dremel or router makes the milling step faster.
