Upgrade your GLOCK Slimline pistol's sighting system with TSA Glow-in-the-Dark Night Sights, precision-machined from 7075-T6 aerospace-grade aluminum for exceptional strength and durability. Engineered exclusively for GLOCK G43, G43X, and G48 models (0.87-inch-wide slides), these sights feature handcrafted glow inserts that recharge naturally under ambient light — no tritium, no batteries, no maintenance — giving you a bright, reliable sight picture in low-light conditions. Each sight set combines rugged construction with customizable style. Available in five premium anodized finishes — Matte Black, Anodized Gold, Crimson Red, Deep Blue, and Coyote Tan — TSA sights let you match your pistol's tone or create a striking contrast for a personalized build. Whether you prefer the classic stealth of black, the bold look of red or blue, or the tactical desert-tan aesthetic, every finish is Type II anodized for long-term color stability and corrosion resistance. Designed for precision shooters and everyday carriers alike, the TSA sight set features a single front glow dot and dual rear glow dots for fast, intuitive target alignment. Installation is simple: the front sight secures with the included screw and Allen wrench, while the rear sight slides and locks into the factory dovetail. The optimized geometry — front sight height 0.165 in (4.19 mm) and rear 0.256 in (6.50 mm) — provides a balanced sight picture and consistent point-of-aim accuracy.
