This SIG SAUER factory adapter plate mounts ROMEO-X series optics to GLOCK MOS-cut slides, letting GLOCK owners run SIG's well-regarded closed-emitter and reflex sights without gunsmithing. Factory adapter plates matter more than most shooters realize: proper footprint engagement, correct screw specs, and precise machining are what keep a red dot zeroed under recoil, and mismatched aftermarket plates are a leading cause of lost zeros. Machined to SIG's standards for a secure, repeatable fit. The simple, correct way to bridge two of the most popular ecosystems in handguns.
