In our old house, I had something similar to what Craig posted, but it wasn't for long guns. If fit between 2 studs and was, I think, 16" tall. I had enough room for multiple guns and other stuff too.

It was an Amsec brand, seemed pretty well made, and came in 3 versions of lock, I think, key, dial combination and electronic combination. I think I found it online for about $300.

I put it in the back of my closet, so it would normally be "hidden" by hanging clothing. Also, since you have the little ones, it'll be up at a height for you to reach, so more difficult for them.

This is what the one that I owned looks like.
