[quote=wis_bow_huntr;3428708]I think its federal that you have to be 21 years of age to carry any handgun in anystate. Some states do not have a Concealed Carry law in place so it would have to be worn where it can be seen.quote]

Most states allow the "open carry" of a gun at the age of 18. there is a whole website committed to this right/law. opencarry . org
