Post number 19 is GREAT!
I have not worn a watch, in a long time, when I did, being right handed, I wore it on my left wrist.
But, I was trained to carry and to shoot left handed as well.
Why?
1. Bad guy may have been watching me (writing a check, whatever) and found out, my strong hand was my right. So in the hopes of taking me down, and focusing on my right hand, my weak hand gave me an element of surprise.
2. It is not uncommon, for folks to focus on "gun" in a serious situation, whereby the gun, and/or gun is hit in a gunfight. So it pays to know weak hand drills, transition drills, or to even have a second gun, weak side, and know how to shoot it, weak handed.
How raised, what you do...
