Keep in mind that there are several bills in both houses of congress that would give CWP holders to carry in any state that issues permits. One of the most popular, and least restrictive was introduced by Senators from the party that is usually more anti-gun. As has been said, the there will be few, if any anti-gun laws passed in the next 4 years. Congress won't shift one way or another dramatically (though the Senate might have a chance of changing hands in two years...I repeat, MIGHT) and the house will pretty much prevent any anti-gun bill from hitting the president's desk.
The biggest concern should be Judicial appointments. And we likely won't see the effects of that for a decade or more.
