Product Overview
The Polymer80 PF45™ 80% Full Size Frame and Jig Kit represents a significant offering for the experienced firearms enthusiast and builder. Designed as a Glock® 20/21 compatible platform, this kit provides the core component for constructing a custom, large-format semi-automatic pistol. It is engineered for individuals who possess a solid understanding of firearm mechanics and seek a personalized project, offering the satisfaction of building a frame to their exact specifications. The PF45™ frame is specifically machined to accept Generation 3, 3-pin components in the potent 10mm and .45 ACP calibers, making it a favorite for those who demand a robust platform for sport shooting, hunting, or advanced training. This is not a firearm; it is a project for a builder to create a unique tool tailored to their needs.
Key Features
- Glock® 20/21 Gen 3 Compatibility: Precisely engineered to accept standard OEM and aftermarket components for Glock 20 (10mm) and Glock 21 (.45 ACP) models, ensuring wide parts availability for your custom build.
- Enhanced Ergonomic Design: Features an integrated extended beavertail and pronounced thumb ledge, promoting a higher, more controlled grip and mitigating slide bite for improved handling.
- Double-Undercut Trigger Guard: Provides additional clearance for the support hand, allowing for a lower, more secure grip and superior recoil management, especially important on larger-caliber platforms.
- Durable Polymer Frame: Constructed from a high-strength, glass-reinforced polymer substrate, offering an optimal balance of lightweight durability and rigidity required for a reliable firearm frame.
- Complete Jig and Tooling Kit: Includes the necessary precision-machined jig, drill bits, and milling bits to properly and safely complete the frame to a functional state, following provided instructions.
- Stainless Steel Rail System: Incorporates embedded stainless steel rails for the slide assembly, ensuring long-term durability, consistent slide cycling, and resistance to wear.
Performance & Applications
The completed PF45™ frame serves as the foundation for a highly capable, full-size pistol suited for specific, demanding roles. Its primary utility is derived from its compatibility with two of the most formidable service pistol cartridges.
1. Hunting and Woods Carry: When built with 10mm components, a completed pistol on the PF45™ platform offers a potent, semi-automatic option for hunters as a sidearm or for dispatching game at close range. The customizable grip and enhanced control features are significant advantages when handling full-power 10mm loads in outdoor environments.
2. Custom Competition or Duty-Style Builds: For the advanced shooter interested in USPSA Limited Division or seeking a personalized duty-style firearm, the .45 ACP configuration built on this frame allows for extensive customization. Builders can tailor trigger systems, stippling, and sights to create a purpose-built tool that matches their exact ergonomic and performance requirements, leveraging the frame’s improved grip geometry.
