I stopped a jeep full of hunters one morning a long time back..before CCW became all the rage..The guy was nervous and stated Officer I want to tell you I have weapons in the car..
My response was..I'll make a deal with ya..you don't pull yours and I won't pull mine..He laughed and went on with a verbal warning..
Ok not on topic..but a favorite story of mine..
I think just handing over the DL & CCW permit without comment are the best if it's just a traffic stop and not saying anything if you don't have to, If you in a non-notify state.
If it goes on beyond a simple stop and release..you might want to let them know..LEO don't care for surprises.
