OK Guys, now you have my curiousity going. As I mentioned I have my Dad's 1911A1 which is a semi-automatic pistol. I also have the original Training/Maintenence manuel that went with it. Half the manuel is about the 1911A1. The other half is about the Colt 45 Revolver. Did you carry the Semi-Automatic or Revolver Colt 45.
Also read recently that although the US Navy issue is now the 9mm many Special Forces (Seal Teams) still use the Colt 45. They prefer the stopping power of the 45.
