Recognize the 2nd Ammendment.
Do not pass any bill, sign any treaty, or issue any executive order that will infringe the right to own or carry a firearm.
As President, you swore to uphold the Constitution. Just because people may vote to support restrictions on firearms, does not give you the right to do so.
Also, recognize that the 2nd Ammendment is not to allow for hunting or self defense. Its purpose is to hold the government accountable to its people.
