About this product
What is the Polymer80 PF9SS 80% Pistol Frame? It is a single-stack, serialized 80% pistol frame designed for finishing compatibility with G43/G43X components. The frame requires completion with a rear rail module and includes stainless steel front rail inserts and a factory-applied aggressive texture. It specifically does not include the milling jig, which must be sourced separately by an intermediate builder.
What is the Polymer80 PF9SS 80% Pistol Frame used for?
The PF9SS is used for building a compact, subcompact 9mm pistol. It accepts Glock G43/G43X OEM or aftermarket slides, barrels, and internal parts kits, resulting in a completed pistol width of 1.02 inches. This frame is the foundation for a personalized, ultra-concealable firearm requiring approximately 2-3 hours of focused machining and assembly work.
How does the Polymer80 PF9SS 80% Pistol Frame compare to a standard Polymer80 PF940V2?
The PF9SS is better for deep concealment, while the PF940V2 is better for general-purpose or competition use. The PF9SS finished build has a slide width of 1.02 inches compared to the PF940V2's 1.26 inches, making it 19% slimmer. This reduction comes at the cost of magazine capacity, as the PF9SS uses single-stack magazines versus the PF940V2's double-stack design. For builders requiring a dedicated tool, we recommend ensuring compatibility with our documented guide on Precision Tested: The Best Drill Bits for Polymer 80% Lower Milling.
What does it weigh and what are the dimensions?
The unfinished/unmilled PF9SS frame weighs 7.8 ounces and measures 7.25 inches in length. The grip module has a width of 1.18 inches prior to final finishing. Once completed with slide and magazine, the total pistol weight typically exceeds 18 ounces.
Who is this NOT for?
This frame is not for a first-time 80% builder or someone without access to a dedicated PF9SS jig. The required machining steps demand familiarity with polymer-specific milling techniques and tolerances. Builders seeking a complete kit should consider a different platform or source the jig and tools separately, as outlined in resources like How to Check Polymer80 Frame Rail Depth Consistency.
What's in the box?
In the box is only the 80% Polymer80 PF9SS frame, one set of stainless steel front rail inserts, and one rear rail module block. You receive no jig, no drill bits, no end mill, and no frame completion parts kit. The shipping box dimensions are 10.5" x 8" x 3".
Is the Polymer80 PF9SS 80% Pistol Frame worth it at $160.99?
Yes, at $160.99 it is worth it for the builder who already possesses a PF9SS-specific jig and seeks the slimmest possible Polymer80 platform. The price reflects the cost of the serialized frame and precision-molded polymer with integrated rails. When compared to the investment for a larger format like our 308 80% Lower – Billet, this represents a focused entry into subcompact building.
