Yes of course the golden rule. I'm usually super Anal when it comes to gun safety, I guess i let my safety guard down some when you see a new gun fresh out of the box with no ammo in the house, knowing very well no NDs or ADs will occur. Atleast I had 2 out of 3 on the list. But it only takes once for an accident so 3 out of 3 should always be used especially if you are posting the darn picture.
