Not be, but to be the safety police, unless you are a full time framer, I would really recommend not using bump fire for the framing gun. I know it is "faster" and is really cool, but I have seen a ton of people nail their hands to walls, put nails in their thighs and injury other people when the gun went off when they did not expect it.
You should treat it with the same level of respect as you would treat a firearm.
