Optics ready plates for Glock 20

The Glock 20 MOS is the full-size 10mm Glock with the Modular Optic System. The cut accepts standard plates in common red dot footprints.

Running a red dot low on the slide means you find the dot quickly and track it through the shot with both eyes open, rather than aligning two iron sights under time pressure. The plate is what turns the Glock 20 into an optic-ready gun: it fills the mounting interface and presents the exact footprint your red dot needs, so the optic sits flat and stays put under recoil.

Compatibility is set by the Glock 20's mounting cut on one side and your optic's footprint on the other — both have to match the plate. Where a co-witness iron matters, look for a plate with an integrated rear sight. Always confirm the exact fit on the individual product page before ordering.
