JakeMcCoy, I missed your question. Jarrett teaches that holding the gun down and stopping recoil is a myth. In fact, he even teaches that shooting minor calibers because you're back on target faster is unimportant.
What he emphasizes is perfect consistency in the way the gun comes back down on target. This is where the laser grips really shine--he'd switch his on and shoot a fast string, and you could watch the laser dot move almost straight up and down with no wasted movement at all. It was like he was controlling it, but really he was just riding the recoil, using his stance and grip to absorb it and bring the gun back.
When I shot with the laser on, the dot was all over the place. I'd fire, it'd fly up, a little left, a lot to the right, back down a foot below the target, back up to the target--and that was a good string for me. I was hitting the target, but you could really see where the difference in speed and quality of hits was coming from. Jarrett's gun comes back to the target like it's got a mind of its own.
He says he's fired about 2 million rounds in his career and the first half-million/million (depending on when he's saying it) were wasted.
