Ameriglo 4XL Tritium Night Sight Set for Glock Green Front Black DEMO/USED
AmeriGlo 4XL tritium night sights for Glock pistols deliver a co-witnessed sight picture tall enough to clear slide-mounted red dot optics and suppressors. If you run a miniature reflex sight on your duty gun, competition pistol, or suppressed defensive Glock, standard iron sights sit too low to be useful. These raised-profile night sights solve that problem—the front post and rear blade are positioned high enough that you'll see clear sight alignment whether you're looking over a suppressor can or co-witnessing beneath an optic. The green tritium front with flat black rear is the go-to setup for low-light shooting, giving you a glowing front post that pairs naturally with a dark, non-glowing rear for a clean sight picture in dim conditions or complete darkness.
Built for serious shooters who demand reliable iron sights as a backup or primary aiming method, these 4XL sights work across all Glock generations without modification. The tritium vials don't require a light source—they glow for years, making them ideal for bedside pistols, duty guns, or any situation where you need to find your sights fast. At the range or in a self-defense scenario, tritium night sights outperform paint dots the moment the sun sets.
This is a demo/used unit, so it may show handling marks or light use, but the tritium and mechanical function are solid. If you're building out a suppressor-ready Glock with an optic and want iron sights you can actually use, the 4XL is the right height for the job.
