Rival Arms RA43G001A Slide Back Cover Plate Glock 17/19 Gen3-4

The Rival Arms RA43G001A Slide Back Cover Plate replaces the factory plastic component with precision-machined aluminum construction. This black anodized upgrade fits Glock 17 and 19 pistols from Generation 3 and 4, providing enhanced durability and a clean aesthetic finish.

What Makes This Different

Unlike standard polymer back plates that can crack under repeated firing stress, this aluminum construction maintains structural integrity through thousands of rounds. The Type III hard anodizing process creates a corrosion-resistant surface that withstands harsh environmental conditions. Precision CNC machining ensures exact fitment without modification to the slide or firing pin assembly.

Key Features

• 6061-T6 aluminum construction for superior strength over factory plastic
• Type III hard coat anodizing resists wear and corrosion
• Direct replacement for Glock 17/19 Gen3 and Gen4 back plates
• CNC machined to exact factory specifications
• Matte black finish matches factory slide coating
• Maintains original firing pin safety function
• No gunsmith installation required

This upgrade proves particularly valuable for competitive shooters and law enforcement personnel who subject their firearms to high round counts and demanding conditions. The aluminum construction eliminates concerns about stress fractures that occasionally develop in factory polymer components. Installation takes minutes with basic tools, and the component maintains all original safety functions without affecting trigger pull or reliability.
