Do I need an adapter?
The Holosun 507K X2 uses the Shield RMSc footprint. If your pistol’s slide is cut for the Shield RMSc footprint (or came with a matching plate), it mounts directly — no adapter needed. If your slide is cut for a different footprint, or uses a plate system such as Glock MOS, you’ll need an adapter plate that provides the Shield RMSc pattern.
Adapter plates that provide the Shield RMSc footprint:
| Slide cut / system | Adapter | Fits | |
|---|---|---|---|
| Glock MOS | Glock MOS Plate — RMSc footprint | Glock MOS models (Gen4 / Gen5) |
