How this slide mounts an opticMilled for the Shield RMSc pattern: an RMSc-pattern optic bolts straight on. S&W doesn't say a Holosun K optic does, and C&H sells a plate to put one on this slide, so this site lists the plate. Nameless Arms, which re-machines these pockets for K optics, says S&W cuts them sloping 0.5 to 0.75 degrees toward the muzzle, enough that some optics run short of elevation.
