I've told the story elsewhere on here, but after almost being shot with my own gun, I no longer tell LEO's I have one, unless it's germane to the conversation.
I can do the whole side of the road, get a ticket thing without once mentioning that I have a gun. I've had several conversations with LEO's about things I witnessed with both our weapons securely holstered and nobody nervous. If the conversation goes bad, and I'm going to get searched, we can revisit the issue then.
If you don't have to tell them, and they aren't going to find out, don't tell them.
