As with any population-wide problem, the solution is "propaganda".
There needs to be proper advertising of the risks and dangers of gun ownership and some propaganda on how to properly secure those things.
Once these ideas are inside people's heads, they'll accept a voluntary gun registration.
After a few years of registrations, all non-registered guns become targets - the government will take them from you if you don't register.
Black market exists and will continue to exist - again, propaganda into preferring registered guns, so you know the gun hasn't been used for illicit ends, or whatever....
In time, the second amendment can be amended by a majority vote.
In case you missed it, this would be a plan to last, at least, 10 years... how many governments will stick with the plan?
