I would like to get two, but can't afford two right now. With the gun purchase I also need a safe, so there is that expense, too. Actually, I've got a longer term plan that involves multiple weapons and safes.
The plan is to have a safe/secure room on each level of the house. That way we could have more than one possible destination depending on circumstances. Within each room would be a gun safe, with one or more fireamrs in it.
So the initial investment is a single shotgun and one safe, and then secure one room with an autolocking keypad door.
I am considering the Sentry Safe Home Defense Center for a quick-access safe. We have two kids, so I'm not leaving the guns out in the open.
