Many users assume that all iron sights are pretty much the same, but I’ve tested dozens to find out otherwise. When I tried the XS Sights 3-Dot Tritium Night Sights for Glock Gen 1-5 +MOS, I was blown away by how quickly I could acquire the target, even in low light. The bright tritium causes no batteries to worry about, and the orange photoluminescent dot on the front makes aligning fast and easy.
Compared to the XS Sights DXT2 Big Dot Tritium Night Sights, which are excellent for those with eyesight issues, the 3-dot sights offer a more versatile, balanced solution for day and night use. The blacked-out rear enhances focus on the front, and the steel construction feels rugged for every day carry. From my testing, the 3-dot sight provides sharp visibility and a reliable, bright glow—making it my go-to pick for the Glock 43x.
