That sure would have screwed up me using my brother's pistol to thwart a robbery, or my daughter using my pistol to kill a rattlesnake.
All of my family knows everyone else's weapons and will use them as required. Don't go throwing a wrench into the works because you are scared.

I was thinking out loud, which in my own case has nothing to do with, and is quite apart from my fearlessness. I like my idea better than the inaccessibility of gun locks and safes where no one can get to them. There are disadvantages enough to choose from in all cases.
