Congrats on your safe. My wife bought me a 10 gun safe several years ago but said I didn't need to fill all the spaces. Bummer!
Be very careful about letting the wife buy you a gun case!
That is just an indiscreet trick they use to keep track of how many guns you own!
They will ask to see how it looks with your guns inside, and then count the empty slots that are left!
Got to stay on your toes!
