These ladies are very skilled at both shooting and educational speaking. Very beginner-friendly, but even longtime shooters can learn from them. And they speak without the stupid macho shit. Dudes, too, should take notice.
For extremely generic instructional talking points, there’s an article on Police One that’ll pop up if you search “8 fundamentals of marksmanship”. Yes, fellow grunts, there are 8.
Consider professional instruction from another woman. Have fun, don’t be too serious; positive reinforcement.
Specific to revolvers, I’m not really qualified to give good instruction yet, but for the low price of free, I offer the following advice:
DA and SA dry fire
.22lr
4-6” of barrel
dry fire
Real sights or RDS, not a snubgutter/ramp
.22lr
Outdoors, just you two, or a third person for comfort
.22lr
dry fire
Finger (thumb) placement and cylinder gap
Electronic earpro
.22lr
Dry fire
Worry about reloads some time in the future only if she becomes infatuated with shooting.
