Description

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 Gen 3 compatible platform, this kit provides the core component for constructing a custom, large-format semi-automatic pistol. It is engineered for individuals who possess the technical skill and desire to personally complete a firearm frame for their own use, adhering to all applicable federal and state regulations. The PF45™ frame is specifically machined to accommodate the potent 10mm Auto and .45 ACP calibers, making it an ideal foundation for a robust handgun suited for demanding recreational shooting, competitive use, or as a dedicated woods/hunting sidearm where these powerful cartridges excel.

Key Features

• Glock® Gen 3 Compatibility: Engineered to work with standard Glock® 20 (10mm) and Glock® 21 (.45 ACP) components, slides, and parts kits, ensuring wide parts availability and proven reliability.
• Durable Polymer Frame: Constructed from a high-strength, proprietary polymer blend, offering a lightweight yet incredibly robust foundation that is resistant to corrosion and environmental factors.
• Enhanced Ergonomic Design: Features an integrated extended beavertail for higher hand placement and reduced slide bite, coupled with a pronounced thumb ledge for improved natural pointability and recoil management.
• Optimized Trigger Guard: Incorporates a double-undercut trigger guard, facilitating a higher, more consistent grip and superior trigger finger placement for enhanced control, especially important with larger-caliber handguns.
• Complete Jig and Drill Kit: Includes the necessary precision-machined jig and drill bits required to properly complete the 80% frame, providing the builder with the tools for accurate milling and drilling operations.
• Stainless Steel Rails: Comes with stainless steel locking block and rear rail modules, providing a hardened, corrosion-resistant interface for the slide and ensuring smooth, long-lasting operation.

Performance & Applications

The PF45™ platform, once completed with quality components, is built to handle the specific demands of large-caliber semi-automatic pistols. Its design directly addresses the control and ergonomic needs of shooters using more powerful cartridges.

1. Backcountry and Hunting Companion: The 10mm Auto configuration is particularly valued by outdoor enthusiasts as a capable sidearm. The PF45™ frame provides a stable, controllable platform for this potent cartridge, suitable for those in areas with wildlife. The polymer construction is also advantageous in varied field conditions due to its lightweight and corrosion resistance.

2. High-Volume Recreational & Competition Shooting: For shooters who participate in practical shooting sports or simply enjoy extended range sessions with a .45 ACP or 10mm, the frame’s ergonomic enhancements—like the thumb ledge and undercut guard—reduce shooter fatigue and improve shot-to-shot recovery. The use of proven Glock® pattern internals contributes to the overall reliability required for competition.

3. Custom Build Platform: For the dedicated hobbyist, this 80% frame serves as a blank canvas. It allows for a high degree of personalization, from slide and barrel selection to trigger upgrades and stippling patterns. Builders can create a handgun tailored precisely to their hand fit and performance preferences, leveraging the ubiquitous aftermarket support for the Glock® platform.
