Keep your eye on the ball; most of our "victories" have not come through legislations per say but through litigation. Be more concerned about the SCOTUS and the lower courts. The rest is just a smoke screen.
The bottom line is anti-gun states will keep trying to pass anti-gun laws until the courts do or do not stop them. Pro-gun states will keep passing pro-gun laws and as stated above the House will keep any federal anti-gun laws in check at least for another two years.
