Polymer80 PF9SS 80% Pistol Frame Only

Build a custom single-stack 9mm with the Polymer80 PF9SS 80% pistol frame only. This receiver blank is designed for compact and subcompact Glock 43 and 43X compatible slides, offering the same ergonomic improvements and modularity as the full-size PF940 series but in a slimline package. The PF9SS frame requires finishing with standard hand tools before assembly, giving you full control over trigger, slide, and grip configuration without the need for an FFL transfer of the frame itself. Each frame is made from reinforced polymer with a steel locking block included, providing a durable foundation for a reliable everyday carry pistol.

Overview

The Polymer80 PF9SS 80% pistol frame only is an unfinished receiver that allows you to complete your own single-stack 9mm pistol at home. It is compatible with Glock 43, 43X, and aftermarket slides, barrels, and lower parts kits. The frame is machined from high-impact Nylon 6 with a 17-4 stainless steel locking block and rear rail system. Because the frame is not yet a functional firearm, it can be shipped directly to your door without an FFL transfer, provided you are legally eligible to own a firearm. The PF9SS features an integrated trigger guard undercut, an extended beavertail, and a 1913 Picatinny accessory rail for lights or lasers.

Features & Specs

This Polymer80 PF9SS 80% pistol frame only ships with the following components: one unfinished frame, one locking block with rear rail, one trigger housing pin, one locking block pin, one front rail pin, one slide lock spring, one slide lock, and one magazine catch. Jigs and drill bits are sold separately. The frame accepts standard Glock 43 magazines and all aftermarket grips or stippling modifications.

Who It’s For

The Polymer80 PF9SS 80% pistol frame only is intended for DIY builders, gunsmiths, and enthusiasts who want to assemble a custom carry pistol from the ground up. It is ideal for shooters who prefer a slim, concealable 9mm platform but want the flexibility to choose their own trigger, sights, and slide. Because the frame is unregistered, it also appeals to builders who wish to construct a firearm for personal use without a serial number or state registration where permitted. This frame is not recommended for first-time builders without some mechanical aptitude, as finishing requires careful drilling and filing to ensure proper fit and function. Always verify local and state laws regarding 80% frame ownership and completion before purchase.

Shipping & FFL

Because the Polymer80 PF9SS 80% pistol frame only is not classified as a firearm under the Gun Control Act, it can be shipped directly to your residence or business without an FFL transfer. No background check or federal waiting period applies to the frame itself. However, once you complete the frame into a functional firearm, it is your legal responsibility to comply with all federal, state, and local laws regarding possession, carry, and transfer. We recommend consulting with a licensed attorney if you have questions about legality in your jurisdiction. Shipping is available to all U.S. states except where local restrictions prohibit 80% frame ownership. No signature is required for delivery, but we recommend shipping to a secure location.
