To create my ultimate gun safe, I started with the Cabela’s Outfitter 86 series, which holds up to 64 long guns ($1,750;, and augmented it with a few upgrades from Liberty Safe. These made the interior more efficient and useful. Some are must-have items. Others are good to have, depending on what it is you’re using the safe to protect.

1. Prevent Rust

The EVA Dehumidifier recharges by plugging it into an outlet. When the crystals turn from green to orange to green, it is ready to go again. You can also consider one of these gun-safe dehumidifiers if you need more inspiration. ($25)

2. Use the Door

Installing a Door Panel adds numerous pockets to store handguns, documents, and other small, valuable items. Cost depends on the size of the panel. (From $89)

3. Hold a Long Gun

The Magnetic Gun Caddy has foam jaws that grip a gun barrel and keep it from falling over. I use mine to prop up and hold a gun while I open the safe. ($14)

4. Organize Handguns

8. Go Digital

Try switching to a keypad entry system. Bill Buckley

Manual dials are a pain. Once you go with an electronic lock, you’ll never want to go back. The lighted keypad makes it easy to open the safe in the dark. ($99)
