To me, it's all about mindset and being alert to my surroundings. Sometimes, that draw 1/2 second before the other guy clears leather is all it takes.
Done that and paused at 1/2 trigger pull because the bad guy froze and took off running. To be blunt and honest too, when things go south, it tends to be FAST! Very fast and sudden!
It's not really different than driving a car; If you're aware of all the traffic around you, you automatically swerve intot he empty lane without thinking when somebody runs a stop sign instead of just slamming the brakes and sliding into them.
