Romeo zero replacement on P365X

What are some of the best optics that are direct bolt-on for SIG P365X and an upgrade from Romeo Zero?

I dont know about bolt on directly, as I think most use mounting plates which would make any of them compatible.

Thanks for the feedback. The 365X and XL come with a precut slide with a cover plate or you can purchase it with the SIG Romeo zero already mounted. It doesn’t require a mounting plate. I’m exploring other upgraded optics that have the same mounting holes and configuration as the Romeo zero so it would be direct mount.

I’m considering the Holosun green dot HE507K-GR X2. It’s a direct bolt on for the X and XL. Was just wanting some educated opinions on other potential options.
