I don't know how it is in all of your guys states but here in Nevada, Las Vegas being my city it is a bit different form what some of you have posted.
In Nevada when an officer pulls you over it will show up that you do have a CCW when he runs you threw scope, you being your vehicle and/or person. It will also show what weapons you are authorized to carry.
Also, in Nevada some say you do and some say you do not need to tell the officer you have a weapon, and some say you have to, now most of my friends are all LEO's with LVMPD and from speaking to them they will tell you the following:
1. You should always tell an officer you have you weapon on you. He already knows from running your plate.
2. If you do have your weapon and are asked if you do and you lie to the officer, you can and will be taken to jail.
I have been pulled over once with my weapon on board and I kept my hands on the sterring wheel, turned on the dome light and rolled down my window. Officer said good evening, I told him I have my weapon, blue card, I.D. and CCW permit on me. He said that is fine and asked me for my I.D. and said he would be right back.
He came back no lees than two minutes later and said have a good night, no ticket.
Having a CCW really makes you think about your roll and responsibilty in everyday life. You have to be mature and have to understand simple laws, and when you can and cannot carry. It is simple rules to live by and you find that when carrying you try to de-escilate situations more than you ever would.
To the OP, I'm not trying to be harsh here, but if you question and or are scared of being pulled over by the police, I do not think you should get a permit. If the police pulling you over causes fear how would you handle your self if you ever did have to pull the trigger?
A lot will changes when bad things happen and your sight picture will be all over the place and you get tunnel vision and time slows down and well you see what im talking about. Being pulled over by the police should not be any concern of your's, pulling the trigger is a bigger worry.
Like I said, I'm not bashing the OP just seeing where your head is
