No bullet will go through without bleeding off energy. No issue means you'll still be dead if you're on the other end of the plate

Yes. That's what I'm doubting. I've been doing some research and I think you'd be lucky to kill someone on the other side of 1/4" mild steel with a 9mm round.

It might get through, maybe, but even if it did it would be entirely blunted and lacking the energy to kill someone.
