Does the Holosun 509T fit the Palmetto State Armory Dagger Full Size / Compact (RMR cut)?

No: the slide is not cut for the Holosun 509T footprint, and no plate listed here bridges it.

No known fit

Enclosed emitter

Nothing in this database bridges the PSA Dagger RMR cut interface to the Holosun 509T pattern. Its own world. Almost always mounted on a dedicated 509T plate; steel plates are the common recommendation. 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.
