Polymer80 PF9SS Jig Kit for PF9SS Frame Blanks

When building a reliable subcompact 9mm platform, precision starts with the tooling. The Polymer80 PF9SS Jig Kit for PF9SS Frame Blanks is the dedicated alignment and drilling fixture required to complete a PF9SS frame blank. This kit is engineered specifically for the PF9SS platform, ensuring that all pin holes, trigger housing pockets, and rail channels are machined to factory-specified tolerances. Without this jig kit, a PF9SS frame blank cannot be finished. It is the essential template that guides every critical cut, making it a non-negotiable component for any builder serious about accuracy and safety.

Designed and manufactured by Polymer80, this jig kit delivers repeatable results. The hardened steel drill bushings prevent bit wander, and the reinforced polymer body resists flex under pressure. For anyone working with a polymer80 pf9ss jig kit for pf9ss frame blanks, the fit between the jig and the frame is tight and consistent, which minimizes the risk of off-center holes or misaligned rails. This kit includes all necessary bits, pins, and alignment tools to complete the frame finishing process.

Overview

The Polymer80 PF9SS Jig Kit is a complete finishing fixture for PF9SS frame blanks. It is not a standalone frame or a firearm; it is the precision tooling required to convert an unfinished frame blank into a functional lower receiver. The kit includes a multi-piece jig body, hardened steel drill guides, a 3mm drill bit, a 4mm drill bit, a 3mm end mill, a trigger housing pin, and a trigger pin. Every component is matched to the PF9SS geometry. This kit is compatible exclusively with Polymer80 PF9SS frame blanks and is not interchangeable with other frame models.

Features & Specs

• Hardened steel drill bushings pressed into a reinforced polymer jig body for long-term durability and hole accuracy.
• Includes two precision-ground drill bits (3mm and 4mm) and a 3mm end mill specifically for pocketing the trigger housing channel.
• Supplied with both trigger housing and trigger pins to verify hole alignment after machining.

Manufacturer specifications confirm the jig is designed for the PF9SS platform only. The jig body measures approximately 6.5 inches in length and weighs under 8 ounces. The drill bushings are pre-installed and require no adjustment. All bits are coated for corrosion resistance. This is a Category: Frames accessory from Polymer80, meaning it is a finishing tool for frame blanks, not a completed frame assembly.
