The nervousness will fade. I still laugh at the looks people give me.
Last week I was OCing a gun on each side while carrying my shotgun, rifle and range bag (with a couple guns poking out of it) up the stairs to my apartment. I had my shotshell bandolier across my chest - fully loaded, of course. New guy moving in saw me and asked, "You a cop?" "Nope." "You security?" "Nope." "Uhhh....":shock:
I just laughed the rest of the way up the stairs and yelled back down at him "You don't have to be a cop or security to carry a gun. It's legal, and it's our right. I've got all these out cause I was just at the range for target practice." He seemed slightly less scared, so I left it at that.
