Extremely nearsighted leading the blind
Wife and I are awaiting our CCW licenses. I've got little experience with guns, my wife even less. We both took the Ohio-CCW version of the NRA Basic Pistol course--10 hours classroom, a bit over 2 hours range time. In addition, I've had the USAF basic training 50 shots towards the woods with a rim-fire M-16 in 1984. I also owned and shot a few thousand rounds from a Ruger .357 in the late 80's, but with no supervision, likely reinforcing bad habits at least as much as developing skill.
We both need practice and training, but realistically I'm going to be her trainer for a while--She's willing to go to the range, but isn't willing to spend more on professional lessons yet, even if I knew how to find a good instructor. I think she can solve a lot of her problems with practice, but I want to avoid getting her into bad habits, and I want to maximize the time I can get her on the range, especially since she's the one who needs to carry. The gun we will be using for now is a Springfield XD40 subcompact.
Her biggest problems are nervousness around guns and a tendency to pull and flinch. She's also inconsistent--She's been able to hit an 8 inch circle at 20 feet with all 9 rounds sometimes, but two magazines later couldn't get a single shot on the 11x17 paper behind it, consistently low and left.
With these facts, what drills would be effective in getting her to the point where she'll be effective if she ever has to use her gun?
