My vault has adjustable height shelving using two on a side rails to hold clips for the shelves. My vault only has handguns. I added homemade shelves.

I use the rubber coated wire racks on the shelves.

I use hooks for hanging some by the trigger guard.
I also use hangers off the shelves on shorter barrels that fit.

I have several long barreled revolvers that must be turned sideways to fit them on the floor of the vault.

I organize by caliber on each shelf rather than manufacturer.

Customizing to Whatever Works is required at the end.
