XS Sights
The XS Sights Minimalist is a low-profile backup iron sight system purpose-built for Glock pistols equipped with the MOS (Modular Optics System) mounting platform. If you're running a red dot or reflex sight on your Glock 19, these backup irons are engineered to sit low in the optics window—far enough out of the way to avoid interfering with your sight picture, but ready to take over instantly if your primary optic fails. That co-witness is factory-tuned, so there's no guessing or custom adjustments needed.
The rear sight features blacked-out, serrated edges to kill glare and keep your focus sharp, while the front sight comes in your choice of a standard blacked-out post or a tritium-dot variant for shooters who need reliable low-light capability. All surfaces are treated with BlackNitride for superior corrosion resistance—important for a sight that's exposed to the elements and potential hard use. The sights are CNC machined from steel and made right here in the USA, built to last longer than the gun itself.
The kit includes both front and rear sights plus red threadlocker to keep everything in place. Installation is straightforward on any MOS-equipped Glock, and these irons are compatible with both RMR and ACRO footprint optics. Whether you're setting up a duty gun, a competition platform, or a defensive carry pistol, the Minimalist gives you a transparent, reliable backup that doesn't clutter your sight picture or slow you down when it matters.
