Guns in MG

Quick question on the use of guns in a Middle Grade novel. I had a scene in my WIP where the bad guy raises a gun menacingly. One scene in the whole book, no shots fired, etc.

But now I am expanding a few areas of the book, and it seems I now need the bad guy to be holding my 12yr old MC hostage at gunpoint. No shots fired or anything either.

So the question is, how much is too much? Where does the line get drawn these days?

Thanks, now that toothpaste gave her example again, I sort of recall that we've discussed this in the past.

I think I was just having a over-reacting-parent-freak-out moment envisioning my kids reading this in 10 years. As it is now, I've started skipping pages with violence in kids books that I read my 2yr olds

As an aside - speaking of over-sheltering kids. My sister shielded her son from all sorts of violence (not watching the news etc.). Recently she switched him to a new preschool. After the first day of school he came home and excitedly told her, "I played with Max, and we played bad guys. I had a gub!"

So now in our house, bad guys will forever wield gubs
