A good instructor would be nice, but I disagree that there's necessarily a deficit in her physical ability. It's probably more mental -- a severe flinch perhaps.

I've seen a lot of novice shooters get flustered at the noise of shooting. It's got to be fun so the noise is not an issue. Another thing I hate is when some d***head thinks it will be fun to sneak a hot load into the cylinder just to get a rise and a cheap laugh. This is a good way to develop a flinch and lose a shooter.

Target loads only, no explosive targets. It really pissed me off when one of the range employees brought an explosive target onto the range while I was trying to get a teen through a BOOM session. Not cool.

Skeet and Trap Clubs usually have an instructor and classes. Shotguns are great home defense tools if the guy/gal holding the gun is an active shooter. No stress fun stuff. Build good habits -- safety first.
