The Glock MOS footprint
The Glock MOS is a pistol optic footprint that mounts with 2 screws (proprietary_plate). 1 red dot optic use the Glock MOS footprint, including the Holosun SCS-M-GR.
Glock Modular Optic System. Slide is machined for swappable adapter plates; the plate carries the actual footprint exposed to the optic. Factory Gen 5 MOS plates support RMR, DPP, Docter, and 507K footprints. IMPORTANT: This applies only to full-size MOS pistols (G17, G19, G34, G45 MOS). The Glock 43X MOS and G48 MOS are misleadingly named - they use a direct RMSc cut, not the MOS plate system.
Footprint specifications are compiled from manufacturer drawings and optic spec sheets.
