New to red dots? What footprint, plate, co-witness and the rest mean

Screw thread trapShadow Systems does not state the slide's thread. It supplies its own screws in an optic kit taped inside the lid of the pistol box, so use those, not the ones in the optic's box.

How this slide mounts an opticThe slim slide is cut for the Shield RMSc pattern, with no plate for the optics Shadow lists: the Holosun 507K and EPS Carry, the Shield RMSc, the Swampfox Sentinel and the Vortex Defender, each with a round or cross spacer at the front of the recess and a screw set (I or II) from an optic kit in the pistol box. Shadow says any optic that fits the recess and lines up with a set of holes can likely be mounted. C&H Precision sells adapter plates for the CR920 for the Trijicon RMR family, the Holosun 407C, 507C and 508T, the 407K and 507K, the EPS family and the 509T.
