Does the Holosun 407C X2 fit the Taurus GX4 TORO / GX4XL?

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

No known fit

Nothing in this database bridges the Taurus GX4 T.O.R.O. direct cut interface to the Trijicon RMR pattern. Deepest optic selection of any footprint. Not interchangeable with RMRcc or RCR despite the shared brand. 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 opticMilled for the RMSc pattern, so Shield RMSc and Holosun K optics bolt straight on with no plate. Taurus lists exactly one adapter for this slide, for the Trijicon RMRcc, and states plainly that an RMRcc will only work on the GX4 T.O.R.O. through it. That is worth reading twice: the RMRcc looks like a small RMR, is not one, and is not an RMSc either.
