HK USP 40 and. 45 differences?

Does anybody know for certain
Wether a usp. 45 trigger group will fit a
usp. 40? Or is the frame bigger?


As far as I know the .45 and the .40 ARE different.... The .45 frame is bigger. Now the .40 and the 9mm are the same frame, just not the .40 to .45.
 
Still might be the same trigger group though... from their site, dimensions:
