Why This One?
From our shop bench in Manhattan, the appeal of this kit is straightforward: it provides a complete, functional foundation for a G19-sized pistol without the serialized frame. We handle a lot of kits, and this one consistently stands out for its build quality. The units we inspect don’t have the visible tooling marks or rough edges you sometimes see on other budget options. It’s a kit that feels complete when you open the box—you get the frame, slide, barrel, and all the small parts needed to finish the build. For Kansas shooters looking for a project for the range, a home defense option, or a concealed carry piece (after proper vetting and break-in), this has been a solid choice. We see repeat customers come back specifically for this kit, which tells us more than any marketing claim ever could.

Honest Assessment
After building a few of these and listening to customer feedback, here’s our straight take.
✅ Pros:
- Complete Kit: You get everything except the magazine and ammo. No hunting for small parts.
- Solid Build Quality: In our inspections, the frames and slides are well-molded and machined. It doesn’t feel cheap.
- Strong Reliability Track Record: Based on both manufacturer specs and the feedback from our customers, these kits run well once properly assembled and broken in.
- Great Platform for Customization: Being Gen 3 Glock compatible means sights, triggers, and barrels are easy to find if you want to personalize it later.
- Practical for Kansas Use: The G19 size is versatile for range use, home defense, or concealed carry (where legal and after ensuring reliability).
❌ Cons:
- Requires Assembly & Tools: You need basic tools (drill, files, punch set) and some mechanical aptitude. It’s not a finished firearm.
- Break-In Period Recommended: Our staff’s observation holds true: plan on putting 50-100 rounds through it for smoothing before considering it for any serious use. This is common for many kits.
- No Serialized Frame: This is a feature for some, but it means you are the manufacturer of the firearm. You must be 21+, it’s for personal use only, and you cannot sell it. Know your federal and Kansas state laws.
Who Should (and Shouldn’t) Buy This
Buy this kit if: You’re comfortable with basic tools and following instructions for a 2-3 hour project. You understand the legal responsibilities of building your own firearm. You want a reliable, functional pistol for the range, home, or carry (post-break-in and vetting) without paying for a brand name on the slide. You like the idea of a G19-sized platform you built yourself.
Skip this kit if: You want a ready-to-shoot firearm out of the box. You’re not comfortable using a drill and files on polymer and metal. You’re unsure about the legalities of building an unserialized firearm in your jurisdiction. You expect absolute perfection in fit and finish without any additional work.
Questions We Get Asked
Is this legal to buy and build in Kansas?
Yes, for personal use, building your own firearm (not for sale or distribution) is federally legal and legal in Kansas, provided you are not a prohibited person. You must be 21 or older to purchase the kit. This is not legal advice, and you should always verify current laws.
What tools do I need?
At a minimum: a hand drill or drill press, a set of small files, a razor blade or exacto knife, a hammer, and a punch set. A vise to hold the jig is very helpful. The kit includes the specific drill bits and the frame completion jig.
How difficult is the build?
Most people with moderate mechanical skill can complete it in an afternoon by following the instructions carefully. The most common issues we hear about are related to the trigger housing pin and ensuring the channel for the recoil spring is clear and smooth. Take your time.
Is it reliable for concealed carry?
Potentially, but only after you’ve thoroughly tested it. Our staff consistently recommends a break-in period of at least 50 rounds of your chosen defensive ammunition with no malfunctions before trusting it for that role. Function check it extensively.
Will it accept aftermarket Glock parts?
Yes. The PF940C frame is designed to be compatible with most Gen 3 Glock 19 components. Slides, barrels, triggers, and sights marketed for Gen 3 G19s should fit. We’ve found this to be true in our testing.
Where can I buy P80 online?
You’re already here. Polymer80Glock is a licensed retailer based in Manhattan, KS. We vet our vendors and handle all ATF compliance paperwork for a smooth transaction. We’ve been stocking this specific kit with consistent success since early 2025.

No. Because this kit contains an unserialized frame (often called an “80% frame” or “receiver blank”), it does not ship to an FFL. It ships directly to your door in discreet, unmarked packaging, in compliance with all federal regulations.
