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

Overview

The Polymer80 PF9SS 80% Single-Stack Frame and Jig Kit is a precision-engineered platform designed for builders who demand a compact, single-stack configuration compatible with Glock 43 components. This 80% frame requires finishing of the fire control pocket, trigger housing pin holes, and front locking block pin holes using the included jig and basic hand tools. The kit delivers a fully functional frame with a reduced grip circumference compared to double-stack frames, ideal for concealed carry applications. The polymer material is sourced from a proprietary blend that maintains dimensional stability throughout the milling process, ensuring proper slide-to-frame fitment when completed with OEM or aftermarket Glock 43 parts.

Features and Specs

The polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) includes a pre-machined frame blank, a universal jig, drill bits, and end mill tooling. The frame features an integrated trigger guard undercut, a textured grip pattern with aggressive stippling on the frontstrap and backstrap, and a Picatinny-style rail section for accessory mounting. The jig is constructed from glass-reinforced nylon and indexes precisely against the frame’s polymer tabs to prevent bit walk during drilling. The frame accepts standard Glock 43 magazines and is compatible with all factory and aftermarket slide assemblies, barrels, and lower parts kits designed for the Glock 43 platform.

• Jig system: Reusable universal jig with hardened steel drill bushings for 0.125-inch and 0.250-inch pin holes; includes alignment pins for frame-to-jig registration
• Compatibility: Glock 43 OEM and aftermarket slides, barrels, recoil spring assemblies, trigger housings, and magazine releases

• Dimensional specifications: Overall frame length 6.2 inches; grip width 0.98 inches; trigger reach 2.7 inches
• Pin hole locations: Fire control pocket pin holes at 0.550-inch and 1.200-inch from rear frame surface; locking block pin hole at 2.400-inch from rear
• Included tooling: Two HSS drill bits (0.125-inch and 0.250-inch), one 0.250-inch end mill, one 3/32-inch alignment punch

Who It’s For

This kit is intended for experienced firearms builders who have completed at least one previous 80% frame project and possess a stable workbench with a drill press or hand drill. The polymer80 pf9ss 80% single-stack frame and jig kit (glock 43 compatible) is suited for individuals who prioritize a slim-profile concealed carry pistol and wish to customize the trigger feel, grip texture, and slide configuration from a bare frame. It is not recommended for first-time builders due to the precision required for the single-stack fire control pocket geometry. The frame is designed for law-abiding citizens who reside in jurisdictions where 80% frames are legal to possess and complete without serialization by the manufacturer.

• Skill level required: Intermediate to advanced; familiarity with drilling and filing polymer materials is necessary
• Tools needed: Drill press or hand drill capable of 500-1500 RPM, calipers for depth measurement, deburring tool, and 220-grit sandpaper
• Legal compliance: Builder must verify local, state, and federal laws regarding 80% frame completion and ownership before purchase
