The important takeaways on safes is, any safe is typically better than no safe, a hidden safe is several times better than most well made safes, and do not be fooled by marketing tomfoolery.
For example UL listings for safes are typically only applicable to the electrical components of digital lock mechanisms, or plugs for safe driers/lighting etc. (Buttons on electronic safes are only warrantied for typically two years as the contacts wear out and your safe becomes inaccessible to you the owner) Safe manufacturers usually give their own very ambiguous ratings for fire protection that are typically unrealistic, and they do their own testing for fire ratings because they cannot pass (nor will they pay for) UL ratings for fire protection, and for many of the major manufacturers found that they could sell a door with thinner steel rolled around what is essentially concrete board that goes under your tiles, make the door thicker with concrete, call the whole thing composite and charge more for it than actually building a decent secure door.
I am not trying to say the whole go big or go home buy a 9934938297$ safe, I just don't want you to be completely misled by marketing, the problem is you cannot just ask the kid behind the counter or in another aisle stocking shelves, because honestly, no one in the store knows whats inside a product, and manufactures are purposefully misleading to get you to buy their most expensive big vault super expensive safe.
What is more likely to happen than getting robbed is have a fire, I'd personally rate having fire prevention/protection well above someone finding a safe and entering it to take its contents, aside from that, neighbors and friends with loose lips sink ships? or houses, or vacations, but you get what I mean, neighbors that know your patterns may not necessarily have any ill will towards you and mention in the workplace overheard by another that you're on vacation for 5 days. (hell all they really need to know is no one will be home for a day) it is more important for you to have operational security than a safe that meets a california rating, for 5minutes against handtools.
That all being said http://gunsafereviewsguy.com/article...ect-your-guns/ has some interesting things to read, has broken a lot of safes to show pictures of how they are made, and has reviews and blogs of different ways to protect a safe against fire, being found, and forced entry. If nothing else its a very interesting read to learn about how safes are made and sometimes how well they are or are not made, and also how to find alternatives to the traditional gun safe.
