I did a good bit or reading on the link jmorris listed. Good info. I don't remember if it was on that site, but I read that it's best to have a dial lock over the keypad lock because the keypad will eventually malfunction. As for size, I only have 10 long guns so I was hoping to fit them on one side and use the selves on the other side for hand guns. So as pretty much all of you said, if I can't place the 10 on one side then it probably won't work for what I'm looking for.
