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

Overview

The Ameriglo Specialty Rear Sight is a serrated black steel rear sight optimized for Glock slimline pistol models, including the 42, 43, 43x, and 48. Engineered with a clean, distraction-free sight picture that eliminates dots or inserts, it allows the shooter's eye to focus naturally on the front post during high-stress defensive situations. The sight features horizontal serrations to break up glare and prevent light reflection in bright environments, while rounded edges minimize the risk of snagging on clothing or holsters during the draw. It utilizes a square-notch geometry measuring .256 inches in height and .165 inches in width to ensure consistent alignment and a repeatable point of aim.
