Polymer80 PF9SS 80% Pistol Frame ONLY
Pros & cons
What works
- Width of 1.02 inches on a completed build — 19% slimmer than a standard Polymer80 PF940V2 frame
- Pre-installed aggressive texture provides a 32% increase in surface grip versus a smooth frame
- Includes serialized rear rail module block — eliminates one sourcing variable for builders
- Weighs 7.8 oz unmilled — keeps final concealed carry weight under 20 oz
Trade-offs
- No included jig — requires a separate $75-$120 purchase to begin work
- Limited to single-stack 6/7 round magazines — not suitable for higher capacity needs
- Rear rail module requires precise hand-fitting — adds 45-90 minutes to the assembly process for proper slide alignment
- Black or FDE finish only — no option for custom Cerakote from the factory

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.

Frequently asked questions
- Is it compatible with Glock 43 aftermarket slides?
- Yes, it is compatible with standard Glock 43 aftermarket slides. The frame uses the G43/G43X footprint, so any slide designed for that model will fit. You must ensure your rear rail module is properly fitted to the specific slide's geometry for reliable function.
- Does this work with Shield Arms S15 magazines?
- No, it does not work with Shield Arms S15 magazines. The PF9SS frame is designed exclusively for single-stack, OEM-specification Glock 43 magazines with a capacity of 6 or 7 rounds. The S15 magazine is designed for the double-stack G43X frame and will not seat.
- Does it include the jig for completion?
- No, it does not include the jig for completion. This listing is for the frame only. You must source a Polymer80 PF9SS-specific jig separately. Completion typically requires a drill press or router, a 3/16" drill bit, and a 5/16" end mill like our <a href="/products/5-16-high-speed-end-mill-for-easy-jig-gen-2/">5/16" High Speed End Mill for Easy Jig® Gen 2</a>.
- How long does shipping take?
- Shipping takes 3-5 business days for processing, plus transit time via USPS or UPS. We do not offer expedited processing on 80% frames. International shipments are restricted and require a 10-15 business day pre-shipment compliance review.
- Can I return it if I make a mistake during milling?
- No, you cannot return a frame that has been milled, drilled, or altered in any way. Our return policy only applies to items in original, unmodified condition with all packaging. Once you begin the machining process, the frame is considered a finished firearm component and is non-returnable.
- What is the frame made from?
- The frame is made from Polymer80's proprietary reinforced polymer blend. It is glass-filled nylon, which provides a tensile strength exceeding 12,000 PSI. The stainless steel front rail inserts are 400-series stainless, heat-treated for wear resistance.
