Description
Product Overview
The Polymer80 PF940Cv1™ 80% Compact Frame and Jig Kit is a comprehensive platform for the experienced firearm enthusiast to build a custom, compact pistol. Designed to be compatible with widely available Glock® 19/23 Generation 3 components, this kit provides a serialized, Polymer 80% frame that requires final machining and assembly by the end-user. It is engineered for hobbyists, builders, and shooters who possess the technical knowledge and tools to complete a frame and who value the personalization and deep understanding of firearm mechanics that a build project offers. The primary use is to create a functional, reliable semi-automatic pistol for legal sporting activities, including target shooting, training, and collection.
Key Features
- Complete 80% Frame & Jig System: The kit includes the precisely molded PF940Cv1 polymer frame and a dedicated, easy-to-use jig with all necessary drill bits. This system guides you through the completion process with accuracy, ensuring proper alignment for critical components.
- Enhanced Ergonomic Design: Polymer80 engineers have rethought the classic platform. The frame features an 18-degree grip angle for a more natural point of aim, an extended beavertail and thumb ledge for superior control, and a double-undercut trigger guard that allows for a higher, firmer grip.
- Glock® Gen 3 Compatibility: Guaranteed to function with standard aftermarket and OEM Glock® 19/23 Generation 3 slides, barrels, and internal parts kits. This ensures vast compatibility and simplifies the sourcing of components for your build.
- Durable Polymer Construction: The frame is manufactured from high-strength, reinforced polymer, offering an excellent balance of lightweight durability and rigidity, contributing to the overall reliability of the finished firearm.
- Factory-Style Grip Texture: The frame comes with an aggressive, molded texture on the grip panels and front strap. This provides a secure, non-slip surface for enhanced handling in various conditions without requiring aftermarket stippling.
- Stainless Steel Rails & Components: The embedded locking block and rear rail module are made from stainless steel, providing a durable, corrosion-resistant foundation for the slide and ensuring smooth, long-lasting action.
Performance & Applications
The completed PF940Cv1 frame serves as the foundation for a versatile, compact pistol suitable for several disciplined applications. Its performance is directly tied to the quality of the components used and the care taken during the assembly process by the builder.
For the dedicated sport shooter, a pistol built on this frame is an ideal platform for structured training and competition in dynamic shooting sports. The ergonomic enhancements—like the thumb ledge and improved grip angle—can contribute to faster, more controlled shot recovery and improved comfort during extended practice sessions. The compatibility with a vast array of Glock®-pattern aftermarket triggers, sights, and slide cuts allows for precise tuning to match personal performance goals.
As a project for the firearms hobbyist and collector, this kit represents the core of a custom build. It allows for a deep, practical education in the function and fitting of semi-automatic pistol components. The builder can select each part—from the slide finish to the connector type—creating a truly personalized firearm that reflects a specific understanding of mechanics and preference, making it a centerpiece of a technical collection.
