Mechanical S&G Lock
Most safes designed to hold "30 guns" don't hold 30 guns unless a number of those guns are pistols or all the guns are basically stacked on top of each other like cordwood. Try to find some pictures of safes filled with guns and you usually won't see 30 rifles/shotguns in a "30 gun safe". Just something to be aware of. Also, like
@diverdon said, most people always make the mistake of buying too small because they rely on the manufacturers capacity estimate.
Fireproof safes are mostly "proof" against fire for a specific duration below a specific temperature and it's a lot shorter and lower than you might expect so don't forego insurance on the content. Also for this reason, separate safe for ammo.
Burglary ratings are also mostly overrated as well. If you're not home and somebody wants it they might put the whole safe on a dolly and wheel it away in the middle of the night or go at it with a metal grinder or saw on one of the side panels which is always thinner than the door. Most safes are good enough to keep guns out of the hands of curious teens or the average smash and grab burglar.
All just opinions of course but meant to be helpful.
Only you can judge if you should involve the hubby or not but it's always worth asking about the return/exchange policy even if you do.
