Do you practice voice commands at the range or during dry fire when you are home? Coming out of the holster and shouting commands?
My voice is one of my best weapons. My voice can become very intimidating. I have made a lot of people think twice about their actions more than once using just my voice.
If I ever have to draw I'm pretty damn confident that what I will say will be very loud and said with confidence but even with knowing that I will continue to practice my voice commands when I'm drawing.
