Gun control is only one way to address the issue of mass shootings.  Also, the NRA has a strong hold on many politicians and it will be hard to break that control.

One way to address this part of the issue to enable gun control is to get the FBI involved in investigating if the NRA crosses appropriate lines in their contributions or control of state and national level politicians.

Then, mass shootings can be controlled to some extent by more background checks, and limitations of the types of automatic guns that are sold in this country.

However, more government support of social programs to support troubled people, effectiely treat the bullies and the bullied, heal divisions between groups in our country, and effectively ensuring that all have enough to eat and educational opportunities would also help address the reasons that people feel isolated and hostile towards others.
