I'm getting a safe with 12ga steel plate on door and all sides. I'm thinking about optimal locations to place it, and it occurred to me that I wasn't sure if a safe is cover or concealment from pistol rounds. It's conceivable that you could be accessing your safe when you have to engage a BG in a HD situation. I'm curious if that steel thickness would be likely to stop 9, .40, and .45 (obviously I know it won't stop rifles). If it can I'll be planning it's positioning on that basis. Thoughts?
