I ran into a similar problem.
I found a Black Friday deal on a gun safe that I just could not pass up. Brought it home and set it up, only to realize I now have "open" slots in my new safe.
I'll need to address that issue.
Yeah, my "friend" lured me into that a couple of months ago. Sure it was going to be a nice trip to the 1500 so he could find some AR accessories. Riiiight, I walked out with an SR9c.
