The RMSc footprint
The RMSc is a pistol optic footprint that mounts with 2 screws (screw_through). 32 red dot optics use the RMSc footprint, including the Burris FastFire C, Bushnell RXC-200 and Bushnell RXU-200.
Shield Sights Mini Compact. Two screws plus four corner recoil bosses (two front, two rear). The dominant micro-optic footprint on subcompact and compact slides. Important variant: this same screw and recoil pattern exists at two physical sizes - 40mm length (micro optics like Shield RMSc, Sig Romeo Zero, Holosun 407K shell) and 46mm length (full-size optics like Leupold DPP, Sig Romeo1Pro). A slide cut for 40mm will not accept a 46mm optic and vice versa.
Footprint specifications are compiled from manufacturer drawings and optic spec sheets.
