How this slide mounts an opticMilled for what Springfield calls its Micro footprint, the Shield RMSc pattern: an RMSc-pattern optic, Springfield's own Hex Wasp included, bolts straight on. A Holosun K optic takes a plate: C&H says its plate is what lets a 407K or 507K go on without modifying the slide's recoil posts. Source: C&H Precision, Hellcat to Holosun 407K / 507K ↗.
