Very interesting post. I wonder if the mods might move it to Tactics and Training . . . it is about gear, but it's more about mindset and planning.
This is exactly why I carry the same guns in the same places, and why I make a point of putting my gun on with my jeans in the morning, and taking it off with them at night. My hand is easily confused, and I wouldn't want it fumbling about looking for something that wasn't there.
