Quick Summary

When installing a Holosun 407C on a Springfield Prodigy, use 6x48 thread pitch screws, not fine-thread Glock screws, to ensure a secure mount. An RMR-cut adapter plate is also necessary. Apply blue Loctite to all mounting screws for both the plate and the optic to prevent loosening from recoil.
