Square Sight Geometry and Tritium Brightness

Square-notch rear sights paired with a glowing front post create a sight picture that doesn't fade when ambient light drops. Night Fision's green tritium fills both front and rear elements, while the yellow outline on the front and white outline on the rear maintain visibility even as the tritium ages. This design works across standard carry and duty applications. For specifics on sight installation, fitment questions, or California purchasing steps, review our California gun-buyer FAQ.

Frequently asked questions

Will these Night Fision sights work on my Glock 26?

These sights are cut for Glock 17, 17L, 19, and 22 models only. The 26 uses a different slide height and requires separate Night Fision sights designed for compact Glocks.

How bright are the green tritium vials on these sights?

Green tritium produces steady glow without batteries. Brightness is consistent in near-total darkness but fades over 10–12 years. Outlined elements stay visible longer as tritium dims.
