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

Screw thread trapS&W doesn't publish this thread: its manual says to mount the optic with the screws that came with the optic, tightened carefully, and gives no thread or torque. Shield Sights, whose RMSc optics fit this cut, sells #6-32 screws for the Shield Plus Optics Ready, and C&H's plates for this slide come with 6-32 plate screws.

How this slide mounts an opticMilled for the Shield RMSc pattern: S&W's own articles say the optics-ready Shield Plus takes the "Shield RMS optic footprint" and "uses the RMSc footprint", and an RMSc-pattern optic bolts straight on. S&W doesn't say a Holosun K optic does (it does say so for the Shield X and the Carry Comp), and C&H sells plates to put a 407K / 507K or an EPS on this slide, so this site lists those. Nameless Arms, which re-machines these pockets for K optics, says it has measured S&W's pockets sloping 0.5 to 0.75 degrees toward the muzzle, enough that some optics run short of elevation. Source: Smith & Wesson, "Shield Plus now optics ready" (the optics-ready Shield Plus takes any Shield RMS optic footprint) ↗; Smith & Wesson, M&P Shield X vs. Shield Plus (the Shield Plus optics-ready models use the RMSc footprint; the Shield X is RMSc/K) ↗; Nameless Arms, M&P Shield pocket re-machine for Holosun K ↗.
On this modelMilled for the RMSc pattern, which S&W's own articles name for it: no plate for an RMSc-pattern optic. S&W's Shield X and Carry Comp pages say RMSc/K; its Shield Plus pages do not mention the K footprint.

Iron sights that co-witness

Typical co-witness by optic type; figures published for this slide are below, with their source.

Sight heights published for 3 optics on this slide

Heights are front / rear in inches, as each sight maker measures its own sights. That's not a deck height, and it doesn't compare across makers to the thousandth. Absolute puts the front sight level with the dot; lower 1/3 and lower 1/5 sit it lower in the window. A sight maker sells a handful of fixed heights, so optics of similar height share one set: the same figures under two optics are the maker's chart saying so, not a copy.
