You cannot stop cartels from dealing drugs, despite massive efforts, what could you do to prevent them from dealing weapons?
Furthemore, while cartels are certainly important, the majority of gun-related homicides within the US are caused by small-time criminals, within a social fabric that facilites small-time illegal gun sales.
Well, it's up to the smart peoples working on this to figure out how to take down the cartels and the big time players that are importing guns illegally into the United States and selling them illegally.

So what are you saying? Focus on the small time criminals?
I don't think there is a solution for the small-time criminals having access to guns, all you can do at this point is try and drive the black market price up, by making it tougher to get new guns.
Either problems require new legislation, which the gun lobby is blocking at every step of the way.
