I doubt the stock sights will give a lower 1/3 co-witness.
Even the RMR, which is a very low profile RDS requires a taller sight set. Unsure how your holosun and a RMR compare.
CZ USA’s web store carries fairly inexpensive sight sets.
The below link should take you to the RMR et al sight set. These are serrated. The 3-dot ones may be cheaper.

I have the extra tall 3-dot set that is necessary for the much taller Leupold DPP. Nothing fancy but does the job.
Good luck.
