This is definitely good advice.
Some points to add that I've seen are those that tend to be afraid of guns will pick the smallest one they see like an airweight .38 snub. They think it won't be as loud and kick as much. Then they go shoot and unknowingly find out it's the worst possible choice they could have made (hard recoil, hard to hit with without lots of practice) and they get turned off to shooting in general. The .38 snub has a lot of reasons for lasting as long in the marketplace as they have which have been touched on here already. In today's world with multiple attackers I'd strongly push her towards a compact doublestack 9mm semi auto like a M&P 9c, Glock 19, baby glock, etc. They are just easier to get proficient with, more pleasant to shoot, hold more ammo which is usually cheaper AND actually more powerful than a .38 Special. All of those are good things...
I got my Sister lined up with CC last year, and went with her to buy a gun. Talked her into the M&P 9 double stack. Her hands are small, and she never shot it well.
Unbelievably, she went on her own to H&H, rented a Ruger LCP W/finger extension , and loved it. She also carries a very small purse, similar to a clutch. Said she was better on target with the LCP vs the M&P, and now she carries the gun vs leaving it in the car as it was too big and heavy for her purse. Who would have thought?
