The XD Gear holster I received with my new 9mm sub compact also fits my 4" 357 XD perfectly. On the wholesale end, the XD Gear package is really a good deal. You get two 10 round compact magazines, a hi-cap magazine with grip filler, and the paddle holster, and it's only $1.00 more than the standard package.
Springfield had an exclusive deal with Accusport for the first 30 days on this deal, but now are releasing the XD Gear package to all the distributors, so you should be seeing them in the stores pretty soon. If your local dealer tries to gouge you on it, remind him that you know he only paid an extra buck for it.
Hope this helps.
