You’re emphasizing the wrong part, imo. The overall societal negligence of mental health, especially for young males, is the biggest ‘fish to fry’. By that I mean the ratio of reduction in gun crime to amount of resources put in is best in addressing that issue head-on, and I feel said issue needs to get a LOT better before that will stop being the case.

After all, what’s better: preventing a homicidal person from getting access to a gun, or preventing a person from becoming homicidal in the first place?
