I was taught to put my weak hand on my belly while my strong hand grabs and lifts the gun from the holster. The weak hand then joins the strong hand on the gun after it is pointed down range. Thus keeping you from sweeping yourself.
Now, if you take the word belly out and replace it with waist, add a bunch of stuff about left hand, right hand mix in a little new guy confusion, and you have someone putting their hand in the wrong spot and a DQ.
Doxa, you now have some real world experience, fortunately you learned that lesson without great harm. Learn from it and move on. Some of the other stuff you wrote about, will help any new 3 gunner, thank you.
