As a condo dweller, I don't think a long gun safe is a viable option. I used to keep them stored in the closet upright, but I was definitely losing barrel finish to the sheetrock and was concerned about them falling down (I realize barrel down is preferred as well). Since I only have a couple at any given time, individual cases seemed like they provided a better storage option. I thought felt cases were suitable for semi-long term storage, but apparently that is not the case. I have also considered some sort of wall rack just to get them out of the way.
