Description
The XS Sights R3D 2.0 is a suppressor-height night sight set designed for Glock 42, 43, 43X and 48 pistols. It combines self-luminous tritium lamps front and rear with a photoluminescent glow dot on the front post to aid alignment in low-light and no-light conditions. The set uses a wider front post and a 0.170 wide rear notch to promote fast sight alignment while the serrated, anti-reflective rear reduces glare. BlackNitride corrosion-resistant finish and CNC-machined steel construction are intended for everyday carry and duty use.
