As I said earlier, I generally won’t say anything during a traffic stop unless there’s a chance the LEO may see my firearm. If there’s that chance, I’d let them know that I’m armed so they’re not surprised.
I did have a situation fairly recently I figure I’ll share. I was doing a walk one weekend and during the walk, I found a handgun in the middle of the road in a small subdivision. I picked it up to make sure it was real and set it on the curb on the side of the road. I called 911 to let them know I had found this handgun. I was carrying an lcp max IWB, but was wearing a snug shirt. So, when the police arrived, I let them know right off the bat that I was carrying and had a carry permit. They didn’t even bat an eye. They took my information, ran a check on the found gun and asked me exactly where I found it, etc… Never asked about my firearm, never asked me to remove it or anything like that.
Funny thing is, when they picked up the gun, the one officer was handling it for a while without checking it. I suggested they check it to see if it was loaded as I didn’t do that when I found it. The officer dropped the magazine and said - yep, it’s loaded. She reinserted the mag and that was it. At that point I said you may want to check if there’s a round in the chamber as well. She kind of gave me a sideways glance but checked the chamber - which had a round in it. lol. I kind of jokingly said - Sorry, not telling you how to do your job, but I’m kind of a gun guy and am just thinking about safety. All was good, but it was kind of interesting. After a short while I asked if they needed me for anything else and they said no, so I went on my way.
