All public schools would teach safe firearms handling and marksmanship as a required course. Long guns in elementary school from grade 6. Handguns added to the curriculum in high school. Trap/skeet, 3-gun, and USMC rifle range as electives.
Public shooting ranges would be available in every city with mandatory facilities available for shotgun, handgun, rifle to 600 meters, sub-machinegun, and belt-fed machinegun ranges. These will be funded by the government.
Adults would pay a one-time firearms tax and have a choice of government provided handgun and rifle. Of course any and all other firearms will be freely available on the open market - no restrictions. Conscientious Objectors would have to pay an additional annual tax for requiring others to provide for their security if they opt out of owning firearms.
Any person publicly voicing an opinion to change any laws and restrict ownership of firearms in any way will be classified as a Conscientious Objector and required to pay the additional tax and have any weapons – firearms, blades, or clubs - confiscated from them. All of their kitchen knives will have the points removed from the tip to a line one inch towards the handle.
Ammunition in military calibers will be publicly subsidized and available for a nominal fee at the public range or shipped to your home at subsidized rates. Each locality can hold elections to add any other calibers to the list of military calibers to be provided to the public in the same manner.
Military service will still be voluntary. Veterans will be able to keep and bear any issue weapons at their personal discretion – provided at cost. This covers small arms, mortars, grenade launchers, artillery, and any other ordinance and vehicles. Maintenance costs will be covered by the owners. If the king requires you to use a weapon to protect the kingdom at the risk of your own blood and your own life you will be allowed to hold that weapon for as long as that blood still courses through your veins.
Part of the citizenship testing process for immigrants will include safe gun handling, and rifle and pistol marksmanship.
The only people for whom open or concealed carry will be restricted will be those with visual or physical impairments to ensure that weapons and training provided will be suitable for their abilities.
