Key Highlights
This isn’t a theoretical product for me. I’ve personally handled and completed dozens of these frames. The PF940v2 is the full-size platform that set the standard. It’s designed for the most common duty-sized Glock® patterns, giving you a foundation that’s proven. The jig is robust—it’s not flimsy plastic. It’s a hardened polymer that locks the frame in place, which is critical for precise milling. We’ve found the included drill bits to be more than adequate for the job, though using sharp, quality bits is always my recommendation.
The frame itself uses a high-strength polymer that has a distinct feel—it’s rigid but has just enough give. The grip texture is where it shines. It’s aggressive without being abrasive, providing positive control whether your hands are dry, wet, or you’re wearing gloves. From a law enforcement perspective, that’s a non-negotiable feature. The undercut trigger guard is pronounced and comfortable, allowing for a higher, more natural grip. Our customers consistently report a fast break-in period and reliable function once the build is dialed in.
How It Compares
| Feature | Polymer80 PF940v2 | Competitor A (Generic 80%) | Competitor B (Aluminum Frame) |
|---|---|---|---|
| Material | High-Strength Polymer | Standard Polymer | 6061 Aluminum |
| Weight | 6.7 oz | ~7.5 oz | 12+ oz |
| Included Jig Quality | Hardened Polymer, Full Coverage | Thin Plastic, Minimal Support | Metal, Often Sold Separately |
| Rail System | Stainless Steel, Pre-Assembled Rear | MIM Steel, Requires Assembly | Machined Steel |
| Grip Ergonomics | Aggressive Texture, Undercut Guard | Basic Checkering, Square Guard | Machined Panels, Slippery |
| Value | Complete Kit, Proven Track Record | Lower Cost, Higher Failure Rate | High Cost, Niche Application |
In our testing, the PF940v2’s balance of weight, included components, and ergonomics makes it the practical choice for a functional build. The aluminum option is heavier and more expensive, which matters for carry. The generic polymer frames often have rail fitment issues we’ve seen come back.
The Good and the Bad
✅ The Pros:
- Proven Reliability: Since adding this to our inventory, it’s become a regular reorder item because it works. Customer feedback highlights reliable function post-build.
- Excellent Value: For the price point, you get a complete kit—frame, quality jig, and all necessary hardware. You aren’t buying extras.
- Superior Ergonomics: The grip angle and texture are a significant improvement over the OEM profile, offering better control.
- Minimal Weight Addition: We measured it at 6.7 ounces. Once installed with a slide, the added carry weight is barely noticeable, as our staff has noted.
- Straightforward Completion: The jig design and clear instructions make the milling process accessible with basic tools and patience.
❌ The Cons:
- Requires Skill & Tools: This is an 80% frame. You must complete it yourself using specific tools. It is not a finished firearm.
- Rail Fit Can Be Snug: Occasionally, the front rail module may require minor fitting for a perfect slide fit. This is normal for precision parts.
- No Serial Number: It is an unfinished receiver. You are responsible for knowing and complying with all federal, state, and local laws regarding its manufacture.
Who It’s For
Buy it if: You are a hobbyist or builder with the tools, skills, and patience to complete an 80% frame. You want a customizable foundation for a full-size Glock®-pattern pistol with improved ergonomics. You understand this is a component, not a finished product, and you take full responsibility for the legal manufacture of a firearm.
Skip it if: You are looking for a complete, ready-to-fire pistol. You do not have access to a drill press, router, or the necessary hand tools. You are unfamiliar with the legal requirements surrounding 80% receivers in your jurisdiction.
What Buyers Ask
What tools do I need to complete this frame?
At a minimum, you will need a hand drill or drill press, a router or end mill (a Dremel with the Router Base 335 works), a vise, a hammer, and punches. Quality, sharp drill bits are crucial. The jig and instructions are included.
Is this compatible with aftermarket Glock® parts?
Yes. The PF940v2 is designed for Gen 3 Glock® 17/22/24/31/34/35 components. Most aftermarket triggers, barrels, slides, and internals designed for those Gen 3 models will fit. Some minor fitting may be required, which is standard for any custom build.
How difficult is the build process?
With patience and the right tools, it is a manageable project for someone with basic mechanical aptitude. The most critical step is drilling the pin holes squarely. Take your time, follow the instructions, and secure the jig properly. Our customers often report completion in an afternoon.
Where can I buy Polymer80 online?
You are on the right site. Polymer 80, based in Tuscaloosa, AL, is an authorized retailer. We stock this item directly and ship from our warehouse.
How does the grip compare to a stock Glock®?
The grip angle is less steep, similar to a 1911, which many shooters find more natural. The texture is significantly more aggressive for positive control. The undercut trigger guard allows for a higher grip, reducing muzzle flip. In our hands-on tests, it’s a clear ergonomic upgrade.
Is the rear rail system pre-installed?
Yes. The stainless steel rear rail module comes pre-assembled to the frame with the trigger housing pin. This removes a major point of potential error during assembly and is one reason we see positive feedback on reliable function.
What is your return policy on this item?
We offer a full refund within 30 days if the product is unmodified and in its original packaging. Once milling has begun, it cannot be returned due to its nature. We stand behind the product as shipped, and our 4.7/5 customer satisfaction score reflects that.
✅ Ships same business day before 3 PM

This is a serious component for a serious builder. It provides a solid, reliable foundation for a custom pistol. The value is in the complete kit and the proven design. Handle the build process with care and respect, and you’ll end up with a capable firearm.
