It isn’t just about kids. For one thing firearms are expensive and valuable, and increases your risks of being broken into. (Most thieves, though, will only target easy victims.)

The other thing is each lock is one more conscious choice with firearms. It’s not much, but it does provide a decision-point where you can choose something else when you find yourself in a mental health crisis.

And for home defense…. It’s almost certain if it changes outcomes… it’ll be hurting you, if it’s stored open. (Now if you carry in your home, that’s different, but also… well we won’t get into that.)
