For those who have not read or seen Rob Pincus's book/DVD "Combat Focus Shooting"--it is awesome. I trained with Rob at Valhalla before I left on my last job in Private Security and I learned a boatload. I now incorporate his drills into my weekly routine and my monthly Rifle/Pistol Transition training.
The key is Rob teaches us to work with what our body does naturally under stress, not try to learn strange techniques to counter it--when we do this, our movements are more fluid, and thus we get faster and put more rounds on target.
It helped me streamline my training routine, and do more with a 50rd box of ammo than I could do with 150rds in a afternoon!
