I ordered a 4227-6 around Christmas, and it was delivered early February. The safe is enormous. I'm talking huge. I have 50 guns in mine (12 or so handguns, and the rest long guns - a mix of ARs, scoped hunting rifles, and shotguns), and I could easily fit another 8-10 long guns (not that I have plans to buy any, honey...).
These are good people to deal with. The videos are on point. I moved my safe off of the pallet by myself, and back into the corner of my garage, using their videos and recommended techniques. A hammer drill from Harbor Freight, combined with a good bit and Tapcon bolts, and that thing is not going anywhere.
I did all of my research online, as a lot of folks do these days. My friends with gun safes have come over and noted how solid, and dare I say sturdy, my safe is compared to theirs and others they have seen.
I'm a huge fan. If I ever need to buy another safe, it will be a Sturdy.
