Our SF Types are issued USPs (2 Commando and SAS) I think they originally got them for the CT Teams and they then (with the involvement in Iraq and Arsecrackestan)moved out onto the hips and gear of guys in the green teams as well. The H&K does not fit my hand as well as a Glock, some of that may well be familiarity as well. I have had a 17 (at least) since the mid 80s when they has slick grips and no serial number plate on the frame.
