Money safe - To store extra credit cards, some cash, checkbooks, spare keys, and TP locate the safe in a dark corner under the kitchen sink behind the pots and pans, dishtowels, and cleaning supplies. The location should be a tight space where a crowbar can't be used to pry the safe. You won't be accessing this safe very frequently so it can be hidden.
Handgun safe - A biometric safe bolted to a wall or cabinet exterior in plain sight and easy access. The best place for a handgun is in a holster on your hip loaded and ready to use.
Rifle safe - A locking wall mount attached under the bed or inside a closet. The rifle should be unloaded and ammo stored in a different but accessible location along with the keys.
