These are the usual figures for this footprint; no maker document is linked for them here yet. What would settle it.
What to knowThe most common cut on carry-size pistols. Whether a Holosun K optic goes straight on depends on the slide, not the footprint: a K optic has recesses for the two front lugs only, so it drops onto an RMSc cut with no rear lugs, but a cut that has all four (the original GLOCK Slimline MOS) needs a plate. Each pistol's page says which it is.
What uses the Shield RMSc footprint?
15 optics use it, 59 pistols are cut for it and 37 plates provide it. Screws M4 × 0.7 usually; torque 10–15 in-lb. Pattern: ≈0.658 in screw centers. The lists below name each optic, pistol and plate.
