The current president hasn't taken any action against gun ownership, even though its apparently a part of his party's platform. Just cause the RNC or GNC says something doesn't mean its canonized law for all who are under their banner.
The only reason he has not so far is because he has to run for re-election and knows that if he did move against gun ownership, he would lose. Give him for more years that he does not have to worry about the backlash and he will try for drastic gun control.
