On the CAG sidearm debate, it is recorded in various formats that they use Glocks and 1911's, operator preference at the same time.
Loads of 1911 evidence about and for Glocks you have the pics already posted, the book "not a good day to die" and the recent KBL book are good examples.
Also I have just finished reading Pete Blaber's book "The mission, the men and me" which mentions that they were using Glocks in Bosnia in the late 90's as well.
