Some ideas for sensible gun control:
1) Guns purchased legally, according to laws in effect at time of purchase, and not used illegally since, are private property and cannot be arbitrarily confiscated by federal, state or local authorities.
2) The  Second Amendment does not need reinterpretation or revision. Private gun ownership and possession is a constitutional right.
3) All gun sales need to be accompanied by an efficient background check of the purchaser. This includes gun show, private and online purchases. 
4) Carry, both concealed and open, should be prohibited with exceptions for hunters and recreational shooters. If you are going hunting, going recreational shooting, carry the gun. If you are going to church, the store, a demonstration and gun-free-zones: Leave the gun at home.
5) Gun manufacturers must be regulated to include the requirement to imprint permanent, non-erasable serial numbers on multiple parts of any gun.
This regulation would also require a serial number or code imprint on all bullets sold. Reloaders, who don’t sell, are exempt.

6) Manufacturers of so-called “smart guns” would be encouraged with substantial tax breaks and/or other federal/local financial incentive to create guns that cannot be randomly fired.
7) Conventional gun purchases would accrue extra taxes, added to both gun and ammunition, with the proceeds dedicated to implement gun control.
8) Weapons classified as “assault” guns (as commonly understood) and all rapid-fire guns or guns capable of automatic fire are prohibited to private owners. They may be owned by clubs to be used by members and cannot be moved off site. Shooting clubs possessing these guns must carry liability insurance. Collectors (to be defined) and museums may also own these automatic weapons. These type of guns already in private hands are private property and cannot be arbitrarily confiscated.
9) Who is barred from gun ownership? Violent felons, those accused of domestic violence until the accusation is dismissed, anyone deemed by psychiatric experts to be mentally unstable and anyone refusing to take a gun safety course and/or refusing to demonstrate safe handling procedures. This is not an all-inclusive list.
10) Controversial gun accessories prohibited: high-capacity magazines. This accessory is not for private ownership, but for shooting clubs only. Current owners of high-capacity magazines have property rights to them. Bump stocks — no private ownership. Current owners have property rights. This is not a complete list of controversial gun accessories.
11) Finally, manufacturers, research institutes and universities must be encouraged with grants and favorable laws to design safer, less-lethal guns intended for use by the general public.
Gun control in the U.S. is far too complex and emotional an issue to be settled quickly. Compromise is essential. Fanatics and extremists on both sides must not be allowed to commandeer the debate. We must plan for the future and accept the idea that it will take more than a generation to reach consensus.
