get a safe ASAP!
The thing is, if you don't have a large collection or if your collection is not that valuable, it's cheaper just to buy more guns or save the money for new guns. Lets say I have a single .22lr handgun which cost me 200 bucks used, are you saying it would be worth it for me to even buy even a cheap desktop handgun safe which cost just about the same amount as this gun does? I live alone with no kids in my home ever. A good safe not only takes up money but precious real estate in your home (not everyone in hawaii has a big house or even a house. Some of us live in a studio/one bedroom apartment...). Transporting a large dedicated gun safe is also a problem, espeically up stairs or up places which don't have elevators. Ideally yes, you should get a safe but you should realize that a safe is not for everyone.
