Product Overview

The Polymer80 PF9SS™ 80% Single-Stack Frame and Jig Kit is the foundational component for building a compact, single-stack pistol compatible with Glock® 43 parts. Designed for the experienced firearms enthusiast and hobbyist builder, this kit provides a challenging and rewarding project that results in a personalized, ultra-concealable handgun frame. As an 80% frame, it arrives unfinished, requiring the end user to complete the final machining steps using the included precision jig and tools. This process is ideal for individuals who value the deep understanding of their firearm’s mechanics, the satisfaction of creation, and the ability to customize ergonomics from the ground up. Its primary use is to serve as the core of a custom-built, semi-automatic pistol suited for personal defense and recreational shooting.

Key Features

• Glock® 43 Component Compatibility: Engineered to guarantee seamless compatibility with factory Glock® 43 slides, barrels, and internal parts, ensuring reliable performance and simplifying the sourcing of build components.
• Complete Frame Finishing Kit: Includes a precision-machined aluminum jig and the necessary drill bits, providing all the specialized tools required to accurately complete the 80% polymer frame to a functional state.
• Enhanced Ergonomic Design: Features an extended beavertail for increased control and reduced slide bite, a double-undercut trigger guard for a higher, more comfortable grip, and an upgraded 18-degree grip angle for improved natural pointability.
• Durable Polymer Construction: The frame is manufactured from a high-strength, reinforced polymer, offering an excellent balance of lightweight durability and rigidity, contributing to the overall reliability of the finished pistol.
• Factory-Style Grip Texture: Comes with an aggressive, molded-in grip texture that provides a secure, non-slip surface for hand placement, mirroring the traction found on many modern production firearms.
• Stainless Steel Locking Block & Rails: Incorporates stainless steel components for the front locking block and rear rail module, ensuring long-term durability, corrosion resistance, and a solid foundation for the slide’s operation.

Performance & Applications

The completed PF9SS™ frame is the heart of a highly concealable and reliable single-stack pistol. Its applications are defined by its compact form factor and the custom nature of its assembly.

Everyday Concealed Carry: Once assembled with a Glock® 43 slide and parts kit, the resulting pistol is a prime candidate for concealed carry. The single-stack design yields a slimmer profile, making it more comfortable for all-day carry and easier to conceal under a variety of clothing. The user-enhanced ergonomics, like the undercut trigger guard, allow for a consistent, high grip which can aid in managing recoil during practice sessions.

Custom Build & Gunsmithing Project: This kit is fundamentally a project for the dedicated hobbyist. It serves as an educational platform for understanding the intricacies of pistol frame function, trigger mechanics, and the relationship between frame geometry and shooter input. The finishing process allows for further personalization, such as additional stippling or frame modifications, creating a truly one-of-a-kind firearm tailored to the individual’s hand and preferences.

Recreational & Training Use: The built pistol is an excellent tool for dedicated training and recreational shooting. Building the frame oneself fosters a intimate familiarity with the platform, which can translate to more confident handling and maintenance. The lightweight polymer frame contributes to a manageable carry weight, making it suitable for extended range sessions focused on defensive drills and marksmanship fundamentals.
