Okay, well they may not be "cop" cops. We refer to them as "Rent-a-Cops".
I live near Ft. Belvior, VA and frequently drive onto post(I'm an army brat). At this post and many others the gov't contracts gate security out to these rent-a-cops. Since I started the whole process of getting my CHP and begining to carry I have started to pay more attention to the guns that people carry.
I saw a Glock-17 in the rent-a-cops holster. As he was checking my ID and stickers I tried to make conversation with him by asking "Is that a Glock-17?" He had a puzzled look on his face so I clarified "is your sidearm a glock-17?"
He said, "No, its just a 9mm."
I said "Oh" I didn't want to argue with him and I didn't have the time to end his ignorance because there were vehicles behind me but I was amazed.
How can you carry a firearm EVERYDAY and not know what kind it is???
Thats like driving your car and only knowing that its a 4 cylinder. "Is that a Honda Civic?" "No its a 4 cylinder".
