Yeah, and when I see a rattlesnake in the yard (quite a common event) or someone forces his way into my house, I'll just ask them to please be so kind as to wait while I go get my gun ready!!
Seriously, when my children were young, it wasn't hard to keep the guns in a rack, out of reach. But, by the time they were able to reach for them, not only they knew better but "securing" them would have rendered them useless. The only exception to this rule was when they had friends over, to play. Then, and only then, the guns were locked in the closet, and my bedroom door closed. Visitors were made aware that my room was out of bounds when playing.
I sense you are sane and responsible ... given you are in a rural or semi rural area.
So many toddler gets daddy’s gun situations are urban and the gun is in the top drawer while the baby is lying on the bed.
You’re smart, you know when it’s safe.
