If it's in a gun free zone and they look respectable, then I may extend them the courtesy of letting them know. That's only because here in TN, no firearm signs hold weight. If I were in GA, who cares? It doesn't bother me if I'm printing and I'm legal.
One loaded mag for an AR, which may change tonight. Then I have my small travel pack, which has 3 loaded 30 round Glock mags, and 2 loaded Glock 19 mags, they all sit nicely in a 5.11 single pistol case with my loaded Glock 19. Then the wife has her loaded Glock 17.
Then a couple EDC pistols.
