• Kit includes: 80% frame, universal jig, 3 drill bits (2.5mm, 3mm, 5mm), end mill, pin punch, and installation wrench
• Compatibility: Accepts all Gen3/Gen4 Glock® 43 lower parts, slide assemblies, and magazines
• Trigger pull weight: 5.5-6.5 lbs (dependent on installed trigger components, not included)
• Finish requirement: Frame requires final sanding and inspection before assembly

Who It’s For

This kit is intended for intermediate to advanced firearm builders who possess the tools and knowledge to complete a polymer80 pf9ss™ 80% single-stack frame and jig kit (glock® 43 compatible). Ideal for custom pistol enthusiasts, concealed carry builders, and shooters who prefer a customized grip angle or trigger guard geometry. The single-stack frame is designed for users seeking a slim, concealable platform without sacrificing capacity. Builders should have experience with hand tool operations, pin installation, and function-checking completed frames. Not recommended for first-time 80% builders due to the precision required for the PF9SS frame rails and trigger housing pin alignment.

• Best suited for: Experienced builders comfortable with drilling, dremel work, and hand fitting
• Not for: Novices without documented 80% build experience or proper workbench setup
• Tool requirements: Vise, drill press or hand drill, calipers, sandpaper (220-400 grit), and thread locker
