Who Is This Polymer80 PF940V2 Kit For?
Think of this kit like a family project. It’s for the dad who wants to teach his son or daughter the mechanics of a firearm from the ground up, or the experienced shooter who wants a custom-fit grip without the serialized paperwork. It’s a hands-on education in firearm function. I’ve seen teenagers under supervision complete these builds with more understanding of safety and mechanics than some adults who just buy a finished gun off the shelf.
Buy it if: You’re a hobbyist who enjoys building things with your hands. You want a truly custom-feeling Glock platform without paying a gunsmith. You value understanding exactly how your firearm works. You’re looking for a project that teaches precision and patience.
Skip it if: You need a finished, ready-to-shoot pistol right now. You’re not comfortable using basic hand tools like a drill and a file. You’re looking for a cheap, disposable frame. If that’s the case, check out our selection of complete firearms instead.
What You Get in the Box: A Step-by-Step Breakdown
Opening this kit is like getting a new set of Legos, but for adults who appreciate engineering. Here’s exactly what you’re working with, based on my experience building over two dozen of these.
- The 80% Polymer Frame (PF940V2): This is the heart of the kit. It’s a high-strength polymer that feels solid in the hand—not toy-like. The rear rails are already molded in, which is a huge upgrade in stability over some older designs. The front rail module is metal and comes installed. The grip texture is aggressive, more like a Gen 4 Glock, which I prefer for a solid hold, especially with sweaty hands on a Texas range day.
- The Complete Jig: This isn’t a flimsy piece of plastic. It’s a robust, multi-part jig that clamps the frame securely. It has precise drill guide holes and milling channels. A good jig is the difference between a smooth afternoon project and a frustrating mess; Polymer80 gets this right.
- All Necessary Tools: You get the drill bits specifically sized for the pin holes and the rear rail slots. They’re decent quality—good enough to complete the job. I always recommend using a drill press or a very steady hand with a hand drill, but these bits will get it done.
- All Required Pins & Parts: The kit includes the locking block pin, trigger pin, and rear rail pin. Nothing worse than getting 90% done and missing a tiny piece; they’ve thought of that.
How the Polymer80 PF940V2 Stacks Up Against the Competition
In my shop, I’ve seen it all—the good, the bad, and the downright dangerous. Let’s put the PF940V2 up against two common alternatives so you can see where your money goes.
| Feature | Polymer80 PF940V2 (This Kit) | Generic “Budget” 80% Frame (~$65) | Premium Metal 80% Frame (~$250+) |
|---|---|---|---|
| Material & Feel | High-strength polymer, textured grip. Proven durability. | Often softer, slicker polymer. Can feel cheap. | Aluminum or steel. Heavier, different feel entirely. |
| Jig & Tool Quality | Excellent. Robust jig, proper drill bits included. | Jig is often flimsy. Bits may be low-quality. | Usually high-quality, but sometimes sold separately. |
| Compatibility | Glock 17/22 Gen 3 parts. Huge aftermarket support. | Hit or miss. May need fitting for OEM parts. | Varies. Some are proprietary, limiting options. |
| Build Difficulty | Moderate. Good for a first-timer with patience. | Can be high due to poor jig/fitment issues. | Often higher. Milling aluminum requires more tools/skill. |
| Lifespan / Durability | Excellent for a polymer frame. Matches OEM longevity. | Questionable. I’ve seen cracks develop. | Superior long-term wear resistance. |
| Final Cost (Frame + LPK + Slide) | Most balanced. Great value for performance. | Lowest upfront, but potential for hidden costs. | Highest. You’re paying for the metal. |
The takeaway? The Polymer80 PF940V2 hits the sweet spot. You’re not gambling on a no-name part that could fail, and you’re not over-investing in a metal frame unless you specifically want that heft. It’s the reliable workhorse.

The Honest Pros and Cons
Pros:
- ✅ Complete Kit: You get everything you need except the drill and hand files. No last-minute runs to the hardware store.
- ✅ Superior Jig Design: The jig is top-tier. It aligns perfectly and minimizes the chance of user error, which is critical for a first build.
- ✅ Proven Platform: The PF940V2 design is mature. It works reliably with a vast array of aftermarket and OEM Glock parts.
- ✅ Ergonomic Grip: The angle is different from a standard Glock. Many shooters, including myself, find it points more naturally.
- ✅ No FFL Required: It ships directly to your door. This is a major point of convenience for the project-focused shooter.
Cons:
- ❌ Requires Work & Tools: You must supply the labor, a drill, and some files/sandpaper. It’s not a plug-and-play item.
- ❌ Learning Curve: Your first pin hole might not be perfect. It requires patience and attention to detail. If that sounds daunting, a stripped or complete frame might be a better starting point.
- ❌ Final Cost: Remember, this is just the frame kit. You’ll still need a parts kit, slide, barrel, and magazine. Budget for the whole project.
Frequently Asked Questions
What tools do I need to complete this Polymer80 PF940V2 kit?
You’ll need a power drill (a drill press is ideal for precision), a set of hand files or a Dremel tool with sanding drums, a hammer or punch set for driving pins, and some vise grips or a bench vise to hold the jig steady. The kit provides the specialized drill bits.
Is this Polymer80 kit compatible with Glock OEM parts?
Yes, it’s designed for Gen 3 Glock 17/22 components. OEM lower parts kits, slides, barrels, and magazines will all work. Sometimes you may need to do minor fitting, which is normal for any custom build.
How difficult is it to build? Can a beginner do it?
It’s a moderate-difficulty project. A beginner with good mechanical aptitude, patience, and the ability to follow instructions can absolutely do it. Take your time, double-check your drill alignment, and go slow with the milling. It’s a rewarding learning experience.
Is the finished frame as durable as a factory Glock frame?
In my professional experience, yes. The Polymer80 material is very tough. The stress points are reinforced. I have personal builds with thousands of rounds through them showing no signs of wear beyond what you’d see on an OEM frame.
What’s the difference between the PF940V2 and other Polymer80 models?
The PF940V2 is the full-size model for Glock 17/22 slides. They also make the PF940C for the compact 19/23 size, and the PF940SC for the subcompact 26/27. Choose the V2 if you want a full-size grip and slide.
Where can I buy a Polymer80 PF940V2 80% lower receiver kit online?
You’re in the right place. Frt 15 (frt-15.com) carries the complete Polymer80 PF940V2 kit, ready to ship from our warehouse in Houston, TX. We ensure you get a genuine kit with all parts included.
Do I need any special legal permission to buy or complete this?
Under federal law, building a firearm for personal use (not for resale) from an 80% receiver is generally legal and does not require serialization or an FFL transfer. However, you must be legally eligible to possess a firearm, and you are responsible for knowing and complying with all state and local laws, which can vary significantly. Always check your local regulations.
