I wonder if that number is the sum of all the permits currently issued or the number of people with permits. I doubt that anyone was able to get a complete list of all the people with permits from all the states and remove duplicates. But they might have made some estimates.
In any case, daughter Kim called me up today to tell me she received her Washington State Concealed Pistol License (CPL) today.
So depending on how the numbers were tallied it could be six million and one licenses are now issued.
