Polymer80 PF9SS Jig Kit for PF9SS Frame Blanks
About this product
The Polymer80 PF9SS Jig Kit is a dedicated single-stack jig and tooling set specifically engineered for machining PF9SS 80% frames to completion. This kit provides all necessary components to transform an unfinished PF9SS frame blank into a functional Glock 43/43X-compatible lower receiver with professional-grade precision. It does not include the frame itself but comes backed by a lifetime warranty covering manufacturing defects.
What is the Polymer80 PF9SS Jig Kit used for?
The Polymer80 PF9SS Jig Kit is used to complete the machining process on 80% PF9SS frame blanks. You'll use the included 5/16" end mill to remove precisely 0.125" of polymer from the fire control group pocket, followed by drilling the three pin holes at 3mm diameter with the included drill bits. The jig maintains ±0.002" tolerance throughout the process, ensuring proper sear engagement and pin alignment critical for safe operation.
How does the Polymer80 PF9SS Jig Kit compare to the 80% AR-15 Easy Jig® Gen 1?
The Polymer80 PF9SS Jig Kit offers superior compact frame specialization compared to the more versatile 80% AR-15 Easy Jig® Gen 1. While both maintain 0.002" machining tolerance, the PF9SS kit's 8.5" length and 4.3" width are specifically optimized for the smaller Glock 43 platform, whereas our 80% AR-15 Easy Jig® Gen 1 accommodates multiple AR-15 lower patterns but requires adapter plates for different models.
What does it weigh and what are the dimensions?
The complete Polymer80 PF9SS Jig Kit weighs 2.1 pounds in its packaging with dimensions of 10.5" × 6.2" × 3.8". The aluminum jig itself measures 8.5" long × 4.3" wide × 1.6" tall, designed specifically to accommodate the PF9SS frame's compact footprint while providing adequate clamping surface for secure machining operations.
Who is this NOT for?
This jig kit is not for builders working with double-stack frames or those seeking a multi-platform solution. If you're building a standard Glock 19-sized frame, you'll need our PF940 series jigs instead. It's also unsuitable for builders without access to a drill press or rotary tool capable of 2000+ RPM, as specified in our more on 80% Lower Receiver Jig Alignment Pin Specifications guide.
What's in the box?
The kit includes one aluminum jig body, three carbide-tipped drill bits (3mm × 75mm), one 5/16" high-speed end mill with 1/4" shank, and all necessary mounting hardware. You get exactly 7 components total, each individually packaged to prevent damage during shipping, plus illustrated instructions covering the 45-60 minute machining process from start to finish.
Is the Polymer80 PF9SS Jig Kit worth it at $129?
At $129, this jig kit delivers exceptional value for dedicated Glock 43/43X builders completing multiple frames. The lifetime warranty and precision machining justify the investment compared to rental programs that typically charge $50-75 per use. For single-build projects, consider our the 80% Lower Jig Rental Program as a more cost-effective alternative.

Pros & cons
What works
- Maintains ±0.002" machining tolerance — critical for proper sear engagement
- Weighs 2.1 lbs complete — 40% lighter than multi-platform jig systems
- Includes carbide drill bits rated for 3-5 frames before replacement needed
- Lifetime warranty covers manufacturing defects — no time limitation
Trade-offs
- No frame included — requires separate $90-120 PF9SS blank purchase
- Single-platform only — cannot be adapted for other Glock models
- Requires drill press or rotary tool capable of 2000+ RPM — not included
- Aluminum jig shows wear marks after 8-10 uses — affects resale value

Frequently asked questions
- Is it compatible with Glock 48 frames?
- No, the PF9SS jig is specifically designed for PF9SS frames which accommodate Glock 43 and 43X components only. The Glock 48 uses a different frame rail configuration and requires separate tooling. Polymer80 does not currently offer a jig for G48-compatible frames.
- Does it include the drill bits and end mill?
- Yes, the kit includes three 3mm carbide drill bits measuring 75mm in length and one 5/16" high-speed end mill with 1/4" shank. These are sufficient for completing approximately 3-5 frames before requiring replacement, depending on cutting technique and material consistency.
- How long does shipping take?
- Standard shipping through USPS Priority Mail takes 2-3 business days for continental US orders. Expedited options are available at checkout for 1-day delivery to most locations. International shipments typically require 7-10 business days plus customs processing.
- Can I return it if I damage the jig during use?
- No, the lifetime warranty covers manufacturing defects only, not user error or damage during machining. Once the jig shows signs of use (tool marks, drilled holes), it becomes non-returnable per Polymer80's policy. We recommend practicing on scrap polymer first if you're new to 80% builds.
- Does this work with aftermarket slide completion kits?
- Yes, the jig produces frames compatible with any Glock 43/43X parts kit, including aftermarket options from Brownells, Lone Wolf, or Strike Industries. The critical dimension is the 3mm pin hole spacing, which this jig maintains within 0.002" tolerance for reliable parts compatibility.
