This is a great example of why you need to pressure test your skills.
Shooting accuracy on the range does not translate directly into accuracy in a real fight. Though factors like shot anticipation, bad trigger control can certainly play a part, I do not believe these are the main reasons. I believe that shooters look at the threat and refuse to allow anything to obstruct their view of the threat, which in this case means the gun sights. After seeing too many good shooters miss horribly low, I’m noticing they aren’t using their sights oftentimes. Worse still, they are not even TRYING to use their sights.
