Polymer80 PF9SS 80% Single-Stack Frame and Jig Kit (Glock 43 Compatible)

Overview

The polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) represents a precision-engineered solution for builders seeking a compact, single-stack platform. Manufactured by Polymer80, this kit is categorized as a frame component and provides the foundational structure for completing a Glock 43-compatible pistol. The kit includes an 80% frame and a dedicated jig system designed to facilitate accurate material removal using standard hand tools. This product requires finishing by the end user and does not include the completed fire control group or slide assembly. The frame is constructed from a high-impact polymer blend and is compatible with aftermarket single-stack components. Builders should verify compatibility with their chosen parts kit prior to beginning assembly.

Features and Specs

The polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) delivers specific engineering tolerances that support reliable function when properly finished. Key specifications include:

• Frame material: proprietary high-strength polymer composite with glass-fiber reinforcement for dimensional stability and impact resistance
• Compatibility: designed for Glock 43 single-stack magazines, slide assemblies, and lower parts kits (OEM and select aftermarket)
• Jig system: includes a reusable CNC-machined aluminum jig with hardened steel drill bushings and alignment pins for precise pocket machining
• Manufacturer-specified rail system: integrated front and rear polymer rails molded into the frame structure for consistent slide travel
• Weight: approximately 2.4 ounces (frame only, unfinished); jig adds approximately 6.8 ounces for the complete kit

• Dimensions: overall frame length of 6.3 inches; grip width of 0.98 inches; trigger guard opening accommodates standard Glock 43 trigger shoes
• Hardware included: three drill bits (two for trigger housing pin, one for locking block pin), two end mill bits, and four alignment pins

• Serial number: the polymer80 pf9ss frame is unserialized as an 80% component; end users should consult federal, state, and local regulations regarding serialization requirements

• Jig retention: frame locks into jig via four compression screws and a rear locating pin; jig is fully reusable for multiple builds
• Material removal: approximately 2.5 cubic inches of polymer must be removed from trigger housing pocket, locking block pocket, and rear rail channel
• Compatible calibers: 9x19mm (9mm Luger) when paired with appropriate barrel and slide

Who It Is For

This polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) is intended for experienced builders who possess a functional understanding of pistol frame finishing. It is suited for individuals who require a compact, single-stack platform for concealed carry or range use and who prefer to complete the frame themselves using basic workshop tools such as a drill press, hand files, and sandpaper. The kit is not recommended for first-time builders due to the precision required in pocket machining and channel finishing. Licensed firearms manufacturers and gunsmiths may also use this frame as a base for custom builds. All end users must comply with applicable firearm laws in their jurisdiction.
