If you live in Florida, not very well at all. The statistics on the first year of effect are in and it looks like they have about a 3.5% increase in homicides, gun deaths, and suicides in spite of some 1300 people having been disarmed.
Like nearly all gun laws, the target is not the criminal or the mentally unbalanced, it's the otherwise normal gun owner. New York, I believe, wants to include using "hate speech" as an excuse to disarm its citizens. I suppose putting a Trump sign in your yard for the election will get you listed.
