The AmeriGlo 4XL Tritium Night Sight Set for Glock puts elevated iron sights within reach of shooters running modern optics on their pistols. These tritium-powered sights—featuring a green front post with green outline and black rear—are engineered to co-witness beneath slide-mounted miniature red dots (like the Glock MOS pattern) and even suppress-height towers. The taller sight geometry means you're not stooping to secondary irons; you get a clean, functional sight picture without compromise, whether your optic is dark or down.
AmeriGlo's 4XL design solves a real problem for optics-ready Glock pistols and suppressor hosts: standard height sights often sit too low for practical co-witnessing, forcing shooters to choose between risers or accepting poor iron sight geometry. These sights eliminate that trade-off. The tritium inserts glow in low light without batteries, and the green-on-green front with blackened rear contrast works for both daylight and night shooting. This is the demo/used unit—fully functional and ready to run.
If you're running an RMR, SRO, or Shield Reflex on your Glock and want irons that actually work alongside it, or you're suppressor-ready and need sights that clear a can, the 4XL is the straightforward answer. Pair them with a quality pistol light, and you've got a serious defensive or duty setup that doesn't rely on a single technology.
| Front Sight Height | .385" |
| Rear Sight Height | .480" |
| Front Post Color | Green with green outline |
| Rear Sight Color | Black |
| Sight Type | Tritium night sight |
| Compatibility | Glock (optic-ready platforms) |
| Design | Co-witness height, suppressor-height capable |
| Condition | Demo/used |
Yes. The 4XL is specifically designed to co-witness with slide-mounted miniature red dot optics like the Trijicon RMR and SRO, as well as other compact reflex sights on optics-ready Glock platforms. The elevated height places the sight picture at a functional level when the red dot is mounted or obscured.
The geometry supports suppressor-height use. The .480" rear sight height clears most suppressor frames, making these suitable for suppressed Glock builds where standard-height irons would be blocked by the can.
No. Tritium is a self-luminous isotope that glows on its own—no batteries, no charging, no electronics to fail. The glow persists for years and works in complete darkness, making it ideal for defensive carry and duty weapons.
The 4XL is taller than standard height sights. The elevated design is purpose-built for Glock optics platforms and suppressors, whereas standard sights are for iron-sight-only guns. If your Glock has a slide-mounted red dot cut, the 4XL is the right choice.
