The XS Optic Mount for Glock 19 (brand part no. GLOM001SM1RMR) from XS Sights lets a Glock 19 MOS slide accept RMR and 507-footprint red dot optics without an aftermarket adapter plate. It’s machined to keep the optic sitting low and tight to the slide, which shortens the sight radius change and keeps co-witness with factory or aftermarket iron sights realistic. For a shooter standardizing on the RMR/507 footprint across multiple pistols, this plate keeps that optic interchangeable onto a Glock 19.
