USP 40 vs 9mm frame/rail size

Are the frames the same size between the two calibers? I am wondering for purposes of mounting a Surefire light to my 9mm. All the advertising and literature I read about them only advertise them as available for the .40 and the .45. I have never seen anything that says "Fits both 9mm and .40".
I am talking about the full size USPs.

9mm and .40 USPs have the same frame and same sized slide. The USP .45, however, is bigger than both. Anything that fits the .40 will fit the 9mm.
