Ameriglo Red Fiber .115 FRONT Black REAR for Glock 42-43-43X-48

The AmeriGlo Red Fiber .115 Front Black Rear sight set for Glock 42, 43, 43X, and 48 combines fiber optic technology with traditional steel construction to deliver rapid target acquisition across varied lighting conditions. This two-piece sight system pairs a red fiber front element with a black steel rear sight, engineered specifically for Generation 1–5 Glock compact and subcompact platforms used in concealed carry, duty, and training environments.

CNC-machined steel construction ensures precise tolerances and durability across extended use cycles. The red fiber optic front sight collects ambient light and channels it through the fiber rod, creating a bright, glowing sight picture that stands out against varied backgrounds—particularly effective in daylight, outdoor ranges, and bright indoor environments where iron sight visibility traditionally suffered. The black steel rear sight provides a clean, unobstructed sight picture and maintains zero shift resistance. This combination delivers the speed advantage of bright front sights without sacrificing rear sight reliability or sight picture clarity.

Operators running compact carry guns in the Glock 42/43 platform—including the slimline 43X and performance-oriented 48—benefit from sights that balance acquisition speed with the inherent accuracy requirements of shorter sight radiuses. The fiber front delivers the visual punch needed for rapid fire while the black rear maintains sight picture consistency. This sight set is not compatible with M.O.S. (Modular Optic System) slides. Made in the USA, this upgrade addresses a primary limitation of factory plastic sights and serves shooters prioritizing speed-focused fundamentals without optic dependency.
