Description
The Polymer80 P80 Gen 1 is the definitive starting point for building a classic 9mm pistol. This isn’t a toy or a novelty; it’s a serious firearm platform built to the original GLOCK Gen 1 specifications. You get the iconic grip angle and profile that started it all, now in a customizable 80% frame. If you want the feel of the original with the freedom to build it your way, this is the kit.
Product Overview
This is a complete Polymer80 P80 Gen 1 pistol kit. It centers on the PF940v1 frame, which mirrors the dimensions and ergonomics of the first-generation GLOCK pistol. The kit provides the core component—the 80% polymer frame—requiring final machining and assembly. This is for builders who appreciate the history and straightforward design of the original, paired with modern aftermarket compatibility. You’re not just buying a gun; you’re acquiring a project that results in a functional, no-frills 9mm Luger pistol.

It will accept standard GLOCK 17 magazines. Note: It is not compatible with Gen 4 or Gen 5 components due to differences in recoil spring assembly and locking block design.

Frequently Asked Questions
What tools do I need to complete this P80 frame?
You will need a drill press or a reliable hand drill, an end mill (typically 3/16″ or 1/4″), and standard gunsmithing tools (punches, hammer, screwdrivers). A router jig is highly recommended for the cleanest results.
Is this compatible with aftermarket GLOCK 17 slides?
Yes. The PF940v1 frame is designed for Gen 1-3 GLOCK 17 slides. The vast majority of aftermarket slides for Gen 3 GLOCK 17s will fit perfectly.
Does this kit include all parts to build a complete pistol?
No. This listing is for the Polymer80 P80 Gen 1 kit, which centers on the 80% frame. You must separately source a slide completion kit (slide, barrel, recoil spring, sights) and a lower parts kit (LPK) to build a functioning firearm.

I don’t write reviews often but glockpistolswitch.com deserves one. The Polymer80 P80 Gen 1 9mm Pistol Kit | 4.49″ Barrel is exactly what I was looking for. Good build quality, snug fit on my G23, and the price was the best I could find after checking multiple sites. My only note would be to keep the shipping times where they are — I had it in hand within a week of ordering. Will be a repeat customer.
