Gun Safe?

After you see and put your hands on a safe in the "TL" class of safes you realize its a totally different animal than any champion, browning, liberty or Cannon. I know a guy with a TL30 and its a beast to say the least. I think the steel is something around 1" for the box and thicker in the door. My cannon you can sink self-tapping screws in.....for comparison. You won't be able to just cut a U in the safe's side and peel in like a tuna can like you can with any box store safe. You are warding off all standard tool attacks and likely only going to be defeated by a pro. It might be annoying to move that massive heavy beast, but your investments are FAR more secure from theft.
 
I found an old Railroad safe on Craigslist for $750, heavy as all get out and gives me piece of mind that the typical smash and grab robber will not defeat it and kids won't get in it.. Then for my replacement peace of mind I have USAA. I know it is cliche, but if it feels good, buy it...
 
I'm limited on space. The irony here is, I'm in a 5700 sq ft house and I don't have room for a safe. Figure that shit out (looks at wife)

Problem is that all of the rooms that could hold a heavy safe are downstairs, and those rooms are purpose rooms already all done (theater room, guest rooms, bathrooms, gym) so there's no actual room where it could go other than in my office/reloading room which has a closet I'm not really using. The only issue is the safe needs to be less than 27" depth or it wouldn't fit with the door shut.

As I see it, other than digging and building a fucking underground bunker in my yard, I have 3 options:

- This Sturdy safe with the 'Magnum Steel' upgrade/level: https://www.sturdysafe.com/collections/gun-safes/products/3224-6 that will be bolted down in my closet

- A giant safe in the garage bolted to the floor, but will sustain 170+ degrees in the garage and I am definitely not too eager to try that

- Build a safe room in the garage and tie HVAC into it; probably the best idea, but it'll be probably 5x the cost of just getting a damn safe.
