Open carry in Delaware is legal I believe but you dont see it much.That being said I saw it in the Acme in Newark today. There use to be a old guy who worked in a hardware store who always did. With a non resident ccw you can carry in DE.
I got a utah somi coukd carry concealed in del as i am close to that border. Before i did i thought , but would not try to do this, that open carry in the carry was legal...gun in plain view...but not concealed. That was my reading. But on the news i heard a baltimore city cop tell a citizen, “ your constitutional rights have nothing to do with the law, and if you don’t move i will arrest you”.
But they prefer you conceal (sign on the door) I have been stopped by kids thinking my cell phone holder is a holster. Tell em no that's concealed their eyes get really big
