I'm a big fan of the NRA Marksmanship Qualification Program. It's self-paced and self-administered. I've used the program to work with a number of shooters. It provides organization and structure that will gradually improve your shooting skills as you work through it. Most people who can follow the instructions will find they have developed into very good shooters by the time they have worked through the Pistol, Defensive Pistol I, and Defensive Pistol II programs through the expert levels in each.
I've served as an NRA pistol instructor, and I've also spent many thousands of dollars in formal training. If you can follow the instructions in the NRA Marksmanship Qualification programs, your money is better spent on ammo for training than on expensive instructors.
