I recently picked up a Colt 1917 45 acp revolver. It is a Army issue gun. Or so it would seem. It says US government property on it. It also has us army on the butt. The thing that seems odd is the fact that the hole for the lanyard ring has never been punched out. I thought all issued handguns had a lanyard loop. Mine has a circle where you can see it should have been. But it is still solid metal. Anybody seen this before?
