Take a look at Sturdy Safe as well. I recommend against electronic locks, for reliability. Fire protection isn't very high on my priorities. I wouldn't put it in the garage, especially if you also have power tools in there that they can use on the safe. If you do put it in the garage, cover...
Can you put it in without the left side in, and then put the left side in after? I'm thinking (guessing) the right side goes in tab-first, then pivot pin, then left side.
I'll add constructive criticism too, with some zing. All the resolution in the world can't compensate for the object being barely in frame.
Sig had that dust cover rubbing problem mentioned on a lot of their customer reviews for some Tacops models.
There's been a few updates to the story. The ATF case was dismissed without prejudice, meaning it can come back.
Also Big Daddy Unlimited copied the trigger with or without a trigger return spring and there's a patent infringement case about that.
