You have a right to protect yourself, your family and your property at any age. I doubt during the Revolution young men were told “ye must be twenty and one to owneth an musket”. When a thief in the night comes, should 1,095 days separate you between life and death? Military members can die at 18, but not keep their side arm? I say as soon as I can learn to use it properly and take responsibility for it, I have the God given right to it, not what some panel of elites dream up.
