I would disagree, if I understand where you are coming from which I may have exactly wrong! 
I went and read legal reviews of the gun case law of the U.S. All the cases. Footnotes on relevant Federal and State cases which were used. The justification for an individual’s right to own, use guns has been disputed throughout the entire history of the case law. Some cases conclude that the right stems from the militia clause, others from the rights of States, others from individuals. It’s pretty mixed.
But what has never been argued is whether individuals have a Constitutional right to own guns. That has never come up, only from whence that right derives. And if one reads the background papers of the founders, it is explicitly clear that they were determined to protect the right of individuals to have guns as well as militias and states.
I believe the last three SC cases got it right. Including, as you say, stressing the point that these rights can be regulated, and have been regulated, and will be regulated.
The real questions is - what can we do to stop gun violence?
