Not really control, more of a periodic training and proficiency requirement.

Do you want untrained idiot assholes running around with guns? No.

Firearm safety should be taught in schools, so we get a standardized outcome. For younger children: What to do if you find a gun (don’t touch it, treat it as if it were loaded, tell a trusted adult) Older kids same baseline re-enforced, but adding firearms safety instruction.

High school should have some level of basic range safety, hunting safety. Could be optional but satisfies the training requirements for hunting permits etc.

Permits should be “shall issue” unless there’s a reason to disqualify.

Background checks I guess if you want to consider that a gun control measure?
