Yes you can do it but let me go into a little more detail.
The 3rd gen full size frames are all the same. That's right, G17,17L,22,24,31,34,35,37. All you need to do is change the *trigger housing to the appropriate caliber and then switch top ends. Keep the 9mm trigger housings for all 9mm top ends. Keep the 40 trigger housing for all 40 & 357 top ends.
*The only exception is the G37. It will require a GAP trigger housing & trigger bar. Once you change these out you can slip on a GAP top end!
