I keep it in the safe now that there are kids in the house. I store my ammo outside of the safe in case of fire. I've rehearsed unlocking the safe, finding it, the ammo, and loading it in the dark.
I keep my Para Ordnance Nitehog in the room. Also under lock & key but I can have it out in about 10 seconds.
