How the PF940v2 Stacks Up Against Competitors
| Feature | PF940v2 | Generic Import Frame | Premium Machined Frame |
|---|---|---|---|
| Material | Reinforced polymer | Basic polymer | Aluminum alloy |
| Rails | Steel reinforced | Plastic | Machined steel |
| Grip Texture | Aggressive stippling | Smooth | Customizable |
| Jig Quality | CNC-milled aluminum | Plastic | None included |
| Price | $220.99 | $65-80 | $300+ |
Why This Kit Wins
The PF940v2 hits the sweet spot between affordability and performance. Unlike cheap imports that flex during firing, this frame maintains zero shift through thousands of rounds. The jig alone would cost $75 if sold separately – we know because we’ve tested third-party jigs that can’t hold tolerance.

Frequently Asked Questions
What tools are needed to complete this frame?
You’ll need a drill press or hand drill, 3/16″ end mill, and basic shop tools. A Dremel helps for finishing work but isn’t required.
Is this legal in my state?
80% frames are federally legal but some states restrict them. We automatically block shipments to prohibited jurisdictions.
How does the grip compare to a Glock?
The PF940v2 uses a 1911-style 18-degree grip angle versus Glock’s 22 degrees – most shooters find it more natural.
Can I use aftermarket Glock parts?
Yes, most Gen3 Glock internals and slides will work. Some fitting may be required for aftermarket components.
Where can I buy Polymer80 frames online?
F1Firearms (f1firearms.net) carries the full Polymer80 lineup with same-day shipping from Arizona.
What’s included in the kit?
Frame, aluminum jig, drill bits, end mill, and all necessary pins/hardware.
How durable is the polymer frame?
We’ve tested these beyond 10,000 rounds with no failures. The steel-reinforced rails prevent wear points.
