Overview

This kit includes the PF9SS frame and the necessary jig to guide your work. The frame is built specifically for Glock 43-compatible slides, barrels, and lower parts, making it a direct path to a reliable, everyday carry pistol. The jig is precision-molded to ensure your drilling and milling stay within spec, so your final build functions as intended. Whether you are new to 80% builds or a seasoned builder, this kit streamlines the process while keeping the hands-on experience front and center.

Features and Specs

• Manufacturer: Polymer80, category: Frames. This is a genuine, serial-number-ready frame designed for the Glock 43 platform.
• Includes the PF9SS 80% frame and a dedicated jig kit. The jig accepts standard hand tools, so you do not need a CNC machine or specialized press.
• Single-stack design for a slim profile. The frame measures approximately 0.98 inches wide, making it ideal for concealed carry holsters and IWB setups.
• Textured grip with finger grooves and a built-in beavertail for improved control. The polymer is reinforced for durability without adding unnecessary weight.
• Accepts all standard Glock 43 lower parts kits, trigger assemblies, and magazine releases. The rail system is compatible with most compact lights and lasers.

When you work with the Polymer80 PF9SS 80% Single-Stack Frame and Jig Kit (Glock 43 Compatible), you are getting a product that balances precision engineering with user-friendly assembly. The jig includes drill guides for the trigger housing pin holes, the locking block pin, and the front rail. Each step is clearly marked, reducing the risk of misalignment. The frame itself is made from a glass-reinforced nylon polymer that resists impact and environmental wear.

Who It Is For

This kit is built for the DIY firearms builder who wants a compact pistol without buying a complete factory model. It suits anyone who enjoys the process of finishing a frame, fitting parts, and troubleshooting their own build. The PF9SS is a popular choice for those who carry daily and prefer a single-stack 9mm for its concealability. It also appeals to hobbyists who want to learn the inner workings of their firearm without the complexity of a full 1911 or AR build. If you have experience with basic hand tools and a steady hand, this kit will reward you with a reliable, custom pistol.

Shipping and FFL

Because the Polymer80 PF9SS 80% Single-Stack Frame and Jig Kit (Glock 43 Compatible) is not a finished firearm, it ships directly to your door without needing a transfer to a Federal Firearms License (FFL) holder. You must be at least 18 years old to purchase, and we verify your age and shipping address. However, once you complete the frame and install a slide, barrel, and other parts, the final product must comply with all local, state, and federal laws. It is your responsibility to understand the regulations in your jurisdiction. We recommend checking with your local authorities before beginning your build. We do not offer returns or exchanges on 80% frames or jigs due to their unfinished nature.

This kit includes the frame and jig only. You will need to source your own Glock 43-compatible slide, barrel, lower parts kit, and magazines separately. We stock a range of compatible components if you want to complete your build in one order. For questions about assembly, compatibility, or legal requirements, contact our customer service team. We are here to help you build right.
