Polymer80 PF9SS™ 80% Single-Stack Frame and Jig Kit (Glock® 43 Compatible) - polymer 80
About this product
What is the Polymer80 PF9SS™ 80% Single-Stack Frame and Jig Kit? It's a Glock® 43 compatible unfinished polymer frame requiring user completion with included tooling. This kit provides the foundation for building a compact single-stack pistol while complying with 80% firearm regulations. The jig and bits are precision-machined to ensure proper alignment during the finishing process.
What is the Polymer80 PF9SS used for?
This frame serves as the foundation for building a compact single-stack pistol compatible with Glock 43 components. It requires approximately 2-3 hours of machining time using standard drill press equipment. The finished product accepts all Glock 43 slides, barrels, and internal parts while maintaining a 1.06" width profile.
How does the Polymer80 PF9SS compare to the ModFuze Compact Spectre frame?
The PF9SS offers superior rail alignment precision with ±0.003" tolerance compared to ModFuze's ±0.005" specification. However, ModFuze frames include pre-installed stippling and require only 45 minutes of completion time. The PF9SS better suits builders prioritizing exact rail alignment over finishing convenience.
What does it weigh and what are the dimensions?
The unfinished frame weighs 5.8 ounces with dimensions of 6.3" length × 4.2" height × 1.06" width. Completed weight increases to approximately 11.2 ounces when assembled with standard Glock 43 components. These measurements make it 0.3" narrower than our .308 80% Lower platform.
Who is this NOT for?
This product is unsuitable for users lacking access to drill press equipment or machining experience. California residents should consult our warranty coverage guide regarding serialization requirements. First-time builders may find the 80% completion process challenging without prior metalworking experience.
What's in the box?
The kit contains one PF9SS 80% polymer frame, one aluminum machining jig, three drill bits (3mm, 4mm, 6mm), and one end mill bit. All components are packaged in anti-static foam with clear orientation markings. The jig features hardened steel guide bushings rated for 500+ drilling cycles.
Is the Polymer80 PF9SS worth it at $220.99?
At $220.99, this kit provides competitive value for experienced builders seeking precise frame alignment. The included jig alone would retail for $89 if sold separately. Compared to completed frames costing $350+, the 37% savings justify the required machining time for technically competent users.

Frequently asked questions
- Is it compatible with Glock 43X slides?
- No, the PF9SS only accepts standard Glock 43 slides due to different rail geometry. The 43X slide is 0.2" longer and requires specific frame modifications. Use only OEM Glock 43 components for guaranteed compatibility.
- Does it fit standard Glock 43 holsters?
- Yes, the completed frame maintains identical dimensions to OEM Glock 43 frames. All holsters designed for Glock 43 will accommodate this frame without modification. Test fit with your specific holster brand before carrying.
- How long does shipping take?
- Standard shipping requires 3-5 business days within continental US. Express shipping reduces transit time to 2 business days. All orders process within 24 hours excluding weekends and holidays.
- Can I return it if I damage during completion?
- No, returns are not accepted for user-damaged 80% frames. Completion errors void all warranty coverage. We recommend practicing on polymer scraps first - consult our drilling guide for technique recommendations.
- Does this work with Shield Arms magazines?
- Yes, the frame accepts all aftermarket magazines compatible with Glock 43. Shield Arms S15 magazines function properly but may require slight feed ramp polishing. Test with your specific ammunition before carry use.
