Can you get FO sites on all XDs ?

Just saw this pic on the Springfield website and wanted to ask for those shooting XDs in Production:

Are FO sights available for all XDs or just the 45s ?

Straight out of the box, probably not, but they use the same mounts/dovetails as Sigs, so I imagine you can get them.
