PF9SS 80% Single Stack Pistol Frame Kit – Gray

Build your own single-stack pistol from the ground up with the PF9SS 80% Single Stack Pistol Frame Kit in Gray. This unfinished polymer frame blank gives builders a starting point for a slim, concealable single-stack pistol project. Glock-style manufacturers mold this frame from a durable polymer blend and finish it in a distinctive gray color that sets your build apart from standard black projects.

Product Description | Specs for PF9SS 80% Single Stack Pistol Frame Kit

This frame ships as an unfinished 80% blank. Manufacturers leave the fire control cavity, pin holes, and other critical features unmachined at the factory. Builders complete the frame using a compatible jig system and manufacturer-specified tooling before it can accept fire control components or function as a firearm.

What’s Included — Frame Kit

• PF9SS 80% single-stack frame blank (unfinished, gray)
• Ships without drilling or machining for fire control components
• Excludes jig, end mill, drill bits, or other completion tooling
• Excludes fire control parts, barrel, slide, or internals

Note: You’ll need a separate compatible jig kit and tooling to complete this frame before installing any fire control components.

Specifications

• Model: PF9SS 80% Single Stack Pistol Frame Kit
• Material: High-strength polymer
• Finish: Gray
• Frame Type: Unfinished (80%) — requires jig-guided completion

• Compatible Caliber (post-completion): Model-dependent — confirm with jig and parts kit specifications

Compatibility

This frame accepts a single-stack fire control group, slide, and barrel once you complete it properly with a matching jig system. It does not function as a drop-in replacement for a factory-complete frame and won’t accept standard lower parts kits until you finish machining it. Confirm jig, end mill, and lower parts kit compatibility with your specific frame variant before purchasing additional components.

Materials & Finish

Manufacturers mold this frame blank from a durable, impact-resistant polymer that withstands machining without cracking or warping when paired with the correct jig and tooling. They mold the gray finish directly into the polymer rather than applying it as a surface coating, so it resists chipping and wear over time.

Customization Options

• Grip Texture: Add stippling or texture during or after completion
• Finish: Apply Cerakote or custom coatings post-completion (may affect warranty where applicable)
• Trigger Guard: Undercut or reshape the trigger guard during finishing
• Engraving: Add professional engraving to the completed frame

FAQs

Q: Can I shoot this frame out of the box? A: No. You receive an unfinished 80% blank that requires jig-guided machining to complete the fire control cavity and pin holes before it can accept fire control components.

Q: Is completing this frame legal? A: Laws on unfinished frames vary by jurisdiction and have changed in recent years.

Q: Does this kit include the jig and tooling I need to finish it? A: No. You’ll need to purchase the jig, end mill, drill bits, and other completion tooling separately, matched to this specific frame variant.

Q: Will standard lower parts kits fit once I complete the frame? A: Only if you complete it correctly with a matching jig — fit depends on precise, accurate machining to spec.
