XS Sights
The XS Sights optic mount for Glock 19 RMR/507 is a precision CNC-machined steel plate designed to give you a rock-solid red dot foundation on your carry or duty pistol. Built for shooters who demand reliability—whether you're training at the range, competing, or depending on your gun for self-defense—this mount transforms your Glock 19 MOS slide into a modern optic-ready platform. The engineering focuses on what matters: thread engagement that resists failure, a recoil lug that keeps your dot stable, and a BlackNitride finish that stands up to the elements.
XS Sights engineered this plate with 30% more thread engagement than standard solutions, a critical detail when you're mounting expensive optics to a carry gun that sees regular use. The additional recoil lug stabilizes the optic and reduces felt recoil force, so your red dot stays zeroed through hundreds of rounds. CNC machining ensures precision fit and repeatability—no wobble, no guesswork. Everything here is American-made steel with a durable BlackNitride surface treatment for enhanced corrosion resistance, so your mount stays reliable whether it sits in a safe or rides in your waistband.
If you run an RMR or 507-footprint optic on your Glock 19 MOS, this is the mount that professionals and competitive shooters trust. It's the foundation your red dot deserves.
