I'm getting ready to purchase my first firearm (handgun) and am wanting a safe not only for the gun, but to also store our important documents and precious metals. My budget for the safe is $400-$500. Not looking for something too big. Cabella's has a liberty brand home safe for $469 that is about 3 cubic feet. Something around that size is what I'm looking for. Any brands and advice you can help will be appreciated as I know very little about safes.
