Does the Holosun 507K X2 fit the Palmetto State Armory Dagger Full Size / Compact (RMR cut)?

No: the slide is not cut for the Holosun K footprint, and no plate listed here bridges it.

No known fit

Nothing in this database bridges the PSA Dagger RMR cut interface to the Holosun K pattern. A subset of RMSc: K optics drop onto RMSc cuts, but a K-only cut has no rear posts for an RMSc optic to index on. Screw thread differs from Shield's M4 — check what shipped in the box. A custom plate or a re-mill would be the only route — check with a plate maker before assuming it can't be done.

How this slide mounts an opticDagger slides have shipped with more than one optic cut. The common one is milled for the RMR footprint and takes an RMR-pattern optic directly. PSA also sells a Dagger RMR plate for the variants that need one, and EGW makes an RMR-to-Docter adapter — so check your slide before buying anything.
