One of my students has been struggling a lot with his shooting, right from the start. He already has some nerve damage from solvents used in his workplace (won't wear gloves), and he over grips to the point of shaking a lot of the time. For some reason I never noticed it when he was shooting his POS M&P, but as soon as he got his stainless Shadow, I saw his big problem, Heeling. as he shoots, his head ducks down, and looks up the sights as he drives the but of the gun down and forward, elevating the muzzle. the slower he shoots the worse it is. At speed drills tonight at 7yds he'd keep them all in the A on a Classic IPSC target (turtle) no problem. Hell often in 3 inches. But slow down and suddenly the head drops and the muzzle angles up. I stand there and direct him and it's like it has a mind of its' own. I need help with this, I want to see him succeed and do well, it bothers me that I couldn't notice it with his M&P, I should have. His hands do have some shake from the solvents as well, but that doesn't explain what he's doing. The shots always being high on the target to over them, is now explained though. Help people, help.
