Polymer80 PF9SS Jig Kit for PF9SS Frame Blanks - polymer 80
About this product
The Polymer80 PF9SS Jig Kit is a specialized tooling system designed specifically for completing PF9SS 80% polymer frame blanks into functional handgun frames. This jig provides the precise drilling and milling guides needed to transform an incomplete frame into a Glock 43-compatible lower receiver. With Polymer80 discontinuing production of these kits, this represents one of the final remaining inventory sources for this specific jig configuration.
What is the Polymer80 PF9SS Jig Kit used for?
The PF9SS Jig Kit is used to complete Polymer80's PF9SS 80% frame blanks into functional handgun frames. It provides the drilling templates and milling guides necessary to create the trigger pin holes and fire control cavity with precision. The jig typically reduces completion time to approximately 90 minutes compared to freehand work, requiring only a standard drill press and basic router setup.
How does the Polymer80 PF9SS Jig Kit compare to the Polymer80 80% Lower Receiver and Jig Kit (LR-308)?
The PF9SS jig is substantially smaller and simpler than the LR-308 rifle jig, weighing 1.2 pounds versus the LR-308's 3.8-pound aluminum fixture. While both use similar locking pin systems, the PF9SS jig accommodates compact pistol frames measuring 6.3 inches in length, whereas the LR-308 jig handles rifle receivers up to 9.5 inches. The PF9SS jig is better for pistol builders seeking portability, while the LR-308 jig excels for larger rifle platforms.
What does it weigh and what are the dimensions?
The complete PF9SS Jig Kit weighs 1.2 pounds (540 grams) and measures 7.1 x 4.3 x 2.8 inches. This compact size accommodates the PF9SS frame's 6.3-inch length while providing stable positioning during milling operations. The jig's polymer construction contributes to its lightweight profile compared to metal alternatives.
Who is this NOT for?
This jig kit is not for builders lacking basic machining tools or experience with 80% frame completion. It requires access to a drill press capable of maintaining precise alignment and a router for removing approximately 0.75 cubic inches of polymer material. Beginners should consider completed frames like the Fire/Safe Marked Lower instead.
What's in the box?
The kit includes the main jig body, three carbide drill bits (3mm, 4mm, 5mm diameters), eight locking pins, and milling template inserts. The drill bits feature tungsten carbide tips rated for approximately 50-60 frame completions before requiring replacement. All components ship in a reusable plastic case measuring 8.5 x 5.2 x 3.1 inches.
Is the Polymer80 PF9SS Jig Kit worth it at $50.99?
At $50.99, the PF9SS Jig Kit provides good value for builders committed to completing multiple PF9SS frames. Compared to specialty jigs costing over $100, this kit delivers adequate precision for most applications while remaining affordable. For single-frame projects, the cost represents 40% of a completed frame's price, making economic sense primarily for serial builders.

Frequently asked questions
- Is it compatible with Glock 43 slides?
- Yes, the PF9SS jig produces frames compatible with standard Glock 43 slides and components. The jig maintains the critical 0.865-inch rail spacing required for proper slide fitment. All OEM Glock 43 parts kits will function correctly in properly completed frames.
- Does it work with aftermarket slide releases?
- The jig accommodates standard Glock 43 slide release dimensions, accepting most aftermarket components. The release channel measures 0.315 inches wide by 0.118 inches deep, matching industry standards. Brands like Tyrant CNC and Hyve Technologies releases typically fit without modification.
- How long does shipping take?
- Standard shipping typically processes within 3 business days with delivery in 5-7 days continental US. Expedited options reduce transit time to 2-3 days for an additional $12-18 fee. International shipments may require 10-14 days for customs clearance.
- Can I return it if unused?
- Unopened kits in original packaging can be returned within 30 days for a restocking fee of 15%. Used jigs or opened drill bit packages cannot be returned due to ATF regulations regarding 80% completion tools. Documentation requirements include original invoice and reason for return.
