I was recently surfing shooting instruction videos and came across this tactic. It seems that James Yeager introduced this technique to Cory of Range Time. Yeager's instance can be seen HERE @ 2:15, and Cory's interpretation can be seen HERE @ 4:11.
Now, to me, it doesn't seem like it holds up to even the smallest of scrutiny: if your firearm goes down, empty or malfunction, wouldn't it make more sense to find cover or at the very least concealment? And, in a worse case scenario instance, would side-stepping two to three feet really save your life? If I'm trying to shoot or injure a moving target, that little side-step maneuver isn't that hard to continue following and keep in my sights.
Is there anything behind this; am I just not seeing it? Or is it just something silly?
