Cross Armory CRG5MCBK Extended Mag Catch Glock Gen 4-5 Black

The Cross Armory CRG5MCBK Extended Magazine Catch transforms magazine changes on Glock Gen 4 and Gen 5 pistols with its enlarged activation surface and precision-machined construction. This aftermarket component addresses the common complaint about factory magazine catch size while maintaining OEM reliability standards.

What Makes This Different

Unlike standard Glock magazine catches that require precise finger placement, the CRG5MCBK features an extended paddle design that increases the activation surface area by approximately 40%. The black anodized aluminum construction provides superior corrosion resistance compared to factory polymer components. Cross Armory machines each catch from 6061-T6 aluminum billet, ensuring consistent dimensions and smooth operation across thousands of magazine changes.

Key Features

• Extended paddle design increases activation surface for faster magazine changes
• 6061-T6 aluminum construction with Type III hard anodizing for durability
• Drop-in compatibility with Glock Gen 4 and Gen 5 pistols (9mm, .40 S&W, .357 SIG, .45 GAP)
• Maintains factory spring tension and engagement specifications
• Low-profile design prevents snagging on holsters or clothing
• Reversible for left or right-handed shooters
• Black finish matches factory Glock components

Competitive shooters benefit from the reduced thumb travel required for magazine changes, particularly during rapid-fire strings or reload-heavy stages. The extended surface allows positive engagement even with wet or gloved hands, making it suitable for law enforcement and military applications. The aluminum construction maintains consistent operation in temperature extremes from -20°F to 140°F without the thermal expansion issues common to polymer components.
