XS Sights Minimalist Glock night sights are available for many Glock and Glock MOS models. These sights feature a tritium front with a high contrast glow dot, glowing brightly in low light conditions. Partnered with a non-tritium rear sight, this duo promises a distinct sight picture. The Minimalist sight design prioritizes your focus on the front sight, with a serrated rear sight that cuts down on glare, and a rear sight ledge that facilitates one-handed slide manipulations. These sights are CNC machined from solid steel bar stock by our in-house machine shop. Compatible with Glock 43X and 48.
