Most mass shootings are done by those who are crazy and/or angry at the world for some reason. I suspect that the rash of mass shootings in recent years is largely a copy-cat phenomenon, just as when one teen in an area commits suicide, there is a rash of teen suicides over that area by teens. It is very difficult to know how to prevent a determined insane person from laying his hands on a gun, especially since most of those who are mentally unbalanced will not be seeking to harm others.
Most deaths by gun come from those who have firearms illegally with the intent to use them for illegal purposes. Turf wars between gangs, retribution and control by mobsters, and personal vengeance kill more people each year than mass shootings, and probably more than mass shootings and personal murders combined. How do we get guns out of the hands of criminals? Answer that, and you will reduce gun violence by over 50%
In addition, the Founding Fathers knew that weapons in the hands of private citizens would discourage government from curtailing liberty. The right to life, liberty, and the pursuit of happiness (by which they meant knowing the good and living by it, an idea that came to them from Greek philosophy) is protected from the tendency of government to curtail liberty by taking on ever greater powers.
