Sorry I'm late lol
Here's a repost with all the info together.
For the handguns on the door I used a type of spool pegs, I bought most of them years ago from an arts and crafts store, if I remember right, at the time they came in a little plastic bag with 12 or so per bag and they didn’t cost much, not long ago I went to buy a few more and they came in a little bag of 3 for $0.99.
My safe has a backing plate behind the fire liner on the door so pegs can be screwed in (there was even a factory peg kit but I didn’t like them), the pegs are spaced for each handgun, I used washers behind some to space them out as needed with certain handguns and on a few I cut the lip of the spool off in some places to clear the front of the trigger guard, each handgun has to be lifted up from the muzzle then pulled out.
Some of the handguns have been on the door for 8 years and I have yet to have any problems with wear on the pistols or have any fall off, they fit very solid.
I hope this helps and feel free to ask if you have any other questions.

The handgun rack on the top shelf is also homemade, It took about two hours to build from two 4’ long x 4” wide boards.
I wanted it to be a wide as the interior of my safe would allow (28” wide), I then did the math on how many I handguns I could put in the rack evenly spaced without them being to close together.
