XS Sight Systems Minimalist Optic Plate and Sight Set Features The XS Sights Minimalist Optic Plate and Sight Set offers a one-stop mounting solution for Glock MOS pistols letting owners mount Trijicon RMR footprint optics while increasing window visibility over typical bulkier plates. The 30% increase in thread engagement compared to standard plates helps prevent optic failure a serious concern for duty and carry pistols that take repeated recoil impulses. An additional recoil lug stabilizes the optic and reduces stress placed directly on the mounting screws. The BlackNitride surface treatment applied to the plate and sights enhances corrosion resistance keeping the parts performing reliably through sweat rain and holster wear. Included in the kit are low-profile backup iron sights that eliminate the need for separate height calculations giving shooters a perfect co-witness right out of the box. The low co-witness keeps the irons positioned just low enough to avoid cluttering the optic s window while still being available as an immediate backup if the optic fails. CNC machined steel sights with a blacked-out serrated rear reduce glare and visual distractions compared to polished sights. Compatible with Glock MOS models 17 19 34 45 47 and 49 this complete kit from XS Sights is available for sale at GrabAGun.
