CB, I only suggested the extra layer of 7 gauge because you seem intent on wanting the 5 gauge safe. Personally, a "base" 7 gauge constructed safe is more than adequate IMO, at least where I live (keep in mind, the door is 5/16 by itself). As mentioned, with a fire liner, you also have an added 14 gauge interior (which you could upgrade to 10 gauge if wanted). For myself, I honestly believe ALWAYS get a bigger safe than you think you will need, particularly if you have anything else of value if you want to protect other than firearms (if you're married, never hurts to work than angle:laughing

I believe you are correct, no safe is "fireproof". If you do some research, you will be amazed at the debate on fireproof safes, particularly when it comes to their actual "testing" and how they are rated (this opens a whole other can of worms up). For myself, since I wanted to actually get something that was "quality made" and offer the greatest chance of helping some items survive a house fire (let's face it, if your house burns down, you may have more to worry about than what is in your safe), it came down to two options. Buy another "cheap" safe and hope for the best, or spend more money.
I'm guessing the majority of your Cannon safes (as well as all those other sub 1k safes at box stores) are made in China with God knows what kind of materials as well as what kind of labor (reason why they are so cheap). What it came down to was the fact I was trusting an American Made company with live American employee's, as well as being able to talk to the owner of that American made company directly myself, and not have him (Terry) try to "sell" me on only his safe, but answer my questions. Since I was spending some "big" bucks (at least IMO on what I'd never thought I'd spend on a gun safe) I wanted to actually talk to the companies whose product I was considering buying. By far, I found Terry's family (wife and daughter as well) more knowledgeable and friendly than the two other companies I had talked with.
Their (Sturdy) videos also helped in my buying decision as it struck me that they were one of the few companies "who put it out there" for people to see what they should look for (I'm not a safe expert by any means, but it made sense to me). The Liberty Presidential line was also in my sights, but I couldn't justify the price difference with the quality, and I also took into account that Liberty imports Chinese made safes as well and stamps their name to them.
If you haven't seen some, I'd suggest looking at a couple...

Please keep in mind, I believe that there are better quality made safes out there, but they are no where in the price range as you will find the Sturdy (well, one in American Security came close, but I had read so much about Sturdy's customer service and was more than please in talking with them that I decided to go with them). I didn't hop on this discussion to push the Sturdy brand, but wanted to point out that sometimes you do get what you pay for. I, like many, were/are satisfied with my cheap safes for keeping kids and guys on dope from my firearms, but I decided to actually look/research what the differences were on the "cheap" safes to the more expensive safes (why don't the majority of people on this forum go to Northern Tool and buy a 7k tactor?). What I found really surprised me. Get a bunch of guys, go in on a cheap safe, do a little research, and see if you can open it. You may surprise yourself.
Let's face it, technically we're not even talking about safes here, but residential security containers.
