In the 43 years I have carried, "every day", unless in a restricted area, even to the beach.
It has never been an issue when going or traveling to an unexpected place, "as long as it was legal to carry". I neither informed or asked permission from anyone. I would never tell a stranger that I had a gun, nor would I trust them to decide if it were safe for me to be in a strange home. Just as I would not ask to inspect their home and see their financial records before entering.
If I am invited to go to a persons home, I am invited as I am, without having to ask their permission on how I live my life, 'especially if I don't know how they live theirs ", or who may be after them while I am in their company.
My close friends all know I carry all the time. It has never come up.
If you feel that it is something to concern yourself with, then you must ask everyone who enters your home if they have any weapons on them, "which I would find very strange. Otherwise you really can't expect a stranger to trust you with that kind of personnel information. They may be an Agent or undercover LEO, or several other kinds of things that would not make it wise for them to entrust a stranger with that information. I am indeed curious how many people have entered home that you would never know carried a gun.
In some businesses I have been in, it was essential to have a handgun available to you at all times.
