If you go to the web site:
http://www.kuci.org/~dany/firearms/all_drills.html
and looks towards the bottom, you will see a section entitled "Federal Air Marshal Tactical Pistol Course (TPC)." This supposedly is what the Air Marshals use to qualify. At the bottom of the section, it says that the info is courtesy of Dean Speir, who I believe frequents this board. You might want to try to get a hold of him for more info...
Hope this helps...
