Ameriglo Specialty Rear Sight for Glock 42/43/43x/48 Serrated Black Protector

The Ameriglo Specialty Rear Sight for Glock 42/43/43x/48 Serrated Black Protector is designed for shooters who demand a clean, distraction-free sight picture for their concealed carry pistols. By eliminating distracting dots or inserts, this rear sight allows the eye to focus naturally on the front post, which is essential for high-stress defensive situations. Whether you are upgrading a factory setup or building a custom slide, this component provides the reliability and visual clarity necessary for precise shot placement. It serves as a rugged alternative to standard polymer sights, offering enhanced durability for daily carry.

This specific model features a .256-inch height and a .165-inch square notch, providing a wide enough window for rapid target acquisition while maintaining sufficient precision. The serrated black finish is a critical design element, as the horizontal serrations effectively break up glare and prevent light reflection from washing out your sight picture in bright environments. Constructed from high-quality steel, the Protector series profile is designed with rounded edges to minimize the risk of snagging on clothing or holsters during the draw. The square-notch geometry ensures a consistent alignment with the front sight for a repeatable point of aim.

While optimized for the slimline series, including the Glock 42, 43, 43x, and 48, this Ameriglo Specialty Rear Sight for Glock 42/43/43x/48 Serrated Black Protector utilizes the standard Glock dovetail for broad compatibility across the platform. It is an excellent choice for users who prefer a "blacked-out" rear paired with a high-visibility or tritium front sight to create a high-contrast aiming system. Installation is straightforward with a standard sight pusher tool, making it a simple yet impactful upgrade for professional duty or personal protection. This sight ensures that your subcompact or micro-compact Glock remains as streamlined and effective as possible.
