These are 7GA steel construction and are pretty secure when you bolt them down.
The regular size safe has room for at least 1 gun in the holster and 1 laying in the bottom backwards with the grip up. The FAS1-Magnum is a little longer and wider and could probably accomidate 2 guns in the bottom (1 on each side of the primary HD gun). Holster styles are interchangeable. While the safes aren't currently lined I am working on offering a lining kit made from speaker box style carpeting as an option. This would also allow me to offer it without a holster attached to the door so you could put a 6" or maybe even an 8" revolver on the FAS1-Magnum safe just laying inside.
