No.

He's not going to change or abolish your 2nd Amendment Rights.

He *might* try to pass through some more restrictions to your rights, though.

Might see another Brady type bill, or Assault Rifle type ban come in to play.

My advice would be to buy that assault rifle, big magazine, etc, now.

No one will come knocking in your door to take your guns away. Just might get harder to find the more interesting stuff that's available now.

PS. At least for now, he's got bigger issues to worry about. You know stuff like the health of our economy, health care, etc, etc. If and when he solves all those problems, or something really bad happens with a person and a gun, than it should be on the back burner for a while.
