Please excuse my rambling on, that's just something us old proud grandpas are prone to do ya know.
No need to apologize.
Pure pleasure to read.
Thanks for sharing.
Teach your kids to shoot bump!
Try having her take a half step forward with her left foot and lean into it a bit.
Also the left thumb over hand works ok with revolvers so they can single action it but if she forgets and uses a semi, it could cause a problem. The left thumb should be just below the cylinder and the right should be to the left of the hammer. There really shouldn't be a difference between the hold on a revolver and one on an semi. It eases the transition between the two.
I know a lot of shooters always say whatever works for them is ok but if they watch the top shooters in the country, they all seem to copy each other.
