You could buy get one from me...
I'll even send it to you for a trial if you like, it's a fist belt slide. I sold the XD, and now have a few holsters for it. If you want one, PM me your address, and I'll send one off to you, if you like it, you can buy it (Majorly cheap) if not, send it back. I have three different kinds, but the leather Fist belt holster is the nicest one I got for that gun.
