The Shield RMSc footprint is the standard for micro-compact and slim-slide carry pistols. It is narrower than the RMR, letting manufacturers cut thin concealed-carry slides for an optic without widening them.
Because it is so common on carry guns, the RMSc has broad support across budget and premium micro red dots alike.

Because the RMSc is so widely copied, some “RMSc-compatible” slides use only the two mounting screws and skip the locating posts. Confirm your slide cut and optic share the same locating features before relying on them, and use the correct screw length for a slim slide so you don’t bottom out.
