To say the President or anyone supports anything with out it coming directly from them is personal opinion, nothing more.
Democrats freely admit their position is one of more gun control. Hillary just did it in an interview with time Russert during the convention. What was interesting about her admisssion was that she recognized the 2nd amendment rights and openly admitted that her support for gun control measures was to appease her voters. The right does the same thing as a concession on other issues. The ownership of guns are an absolute right and any conditions are unconstitutional.
