It’s too dangerous with my children around. Too many stories.
In a similar situation and looking at options for a safe that can address this concern.
Another option that I am considering (assuming there are no legal issues) is keeping it stored at a relative who has guns and who I trust.
Perhaps I am being naive, but I am not (yet) scared that I'll be in a situation where I'll need on a moments notice. But I don't want to push off buying it until things get to that point, since;
1 - I want to be able to practice with it now.
2 - If ח"ו it gets to that point, I don't want to rely on being able to get to a store that will sell me a gun.
