It is not clear from their website whether XDs have a polyginal rifling as a standard. Does anybody know if yes?

Thanks

thanks. What are the advantages/disadvantages of polygonal/conventional rifling?

There has been a lot of previous discussion about the pros and cons about each type. Try a search. To sum some of what I remember...

Polygonal Pros:
"Better" bullet to bore seal - higher velocity due to less gas loss (or less velocity due to more friction?)

Cons:
Can't shoot lead bullets, lead fouling could cause higher friction and case blowouts...
