My safe, Cannon, came with a door organizer.
It has pockets for pistols and some zippered pockets for.......stuff.
I don't put pistols in the pistol pockets. In my mind I can hear any pistol in those pockets falling out and smashing to the floor of the safe when I went to close it.
I bought some pistol racks from Manaboutracks to store my pistols.
The door pockets/holsters are used to hold.......stuff. Knives, smaller holsters, some coinage, wife's jewelery.....stuff, but not Firearms.
