The national concealed weapons permit age minimum may soon be changed to 18 years old. Currently, the conceal carry age in most states is 21. In others, you are allowed to carry certain registered weapons at 18. Vermont allows people as young as 16 to conceal carry and some states don’t specify an age at all. The argument shouldn’t be difficult to make: 18 is too young for a person to be licensed to carry a deadly weapon.
When camping, weapon-use is understandably different. When you’re camping you’re usually surrounded by experienced shooters and you’re usually hunting animals.
