There are people who just love to collect different kinds of gun. I don’t know what made them collect this kind of collection. I do not know if you know if you know someone who loves gun. As for me, I don’t know anyone. I just know that carrying a gun needs license and permit to carry.
But if you if you own a firearms I would advise you to have gun safes at home. It is important to hide your firearms in a safe place especially if you have children at home to avoid horrific accident.
