Polymer80 PF9SS Jig Kit for PF9SS Frame Blanks - polymer 80
About this product
The Polymer80 PF9SS Jig Kit for PF9SS Frame Blanks is a specialized tooling system for completing Glock 43-compatible 80% polymer frames. This kit provides the necessary drilling and milling guides to convert an unfinished PF9SS frame into a functional firearm receiver. Production has been temporarily suspended, making remaining inventory the final available stock.
What is the Polymer80 PF9SS Jig Kit used for?
This jig kit is used to complete Polymer80 PF9SS 80% frame blanks into functional pistol frames. The jig provides precise drilling guides for pin holes and milling templates for rail slots and recoil spring channel. It requires a drill press or hand drill and standard workshop tools to complete the machining process.
How does the Polymer80 PF9SS Jig Kit compare to the Polymer80 80% Lower Receiver and Jig Kit (LR-308)?
The PF9SS kit is specifically designed for compact Glock 43 platform frames, while the LR-308 kit serves AR-10 platform receivers. The PF9SS jig weighs 420 grams compared to the LR-308's 780 grams, making it more compact for pistol-sized builds but with significantly different application purposes.
What does it weigh and what are the dimensions?
The complete jig kit weighs 420 grams and measures 180mm x 120mm x 45mm when assembled. This compact size allows for bench-top operation without requiring large vise setups. The aluminum jig blocks account for 380 grams of the total weight, providing stability during machining operations.
Who is this NOT for?
This kit is not suitable for beginners without prior gunsmithing experience or proper machining tools. Users must have access to a drill press, end mills, and understanding of frame finishing techniques. Those seeking ready-to-use firearms should consider complete pistols rather than 80% build kits.
What's in the box?
The kit includes one aluminum jig assembly, three drill bit sizes (3mm, 4mm, 6mm), one 3/16-inch end mill, and mounting hardware. All components are packaged in foam-secured packaging to prevent damage during shipping. The drill bits are standard high-speed steel suitable for polymer machining.
Is the Polymer80 PF9SS Jig Kit worth it at $50.99?
At $50.99, this kit represents good value for experienced builders completing PF9SS frames. The price includes all necessary tooling except the drill press, saving approximately $25 compared to sourcing components separately. Given the production halt, this may be the final opportunity to purchase this specific jig system.
