The Glock G45 MOS uses a mounting-plate system: the slide takes a plate that matches your optic’s footprint, so most red dots fit once you have the right plate. Standard 9mm MOS cut: plate 02 for RMR/Holosun C-footprint, 04 for DeltaPoint Pro/EFLX, 01 for Docter/Vortex, 03 for C-More; Gen5 boxes usually include plate 02 only.
