good HD options for a small-statured single mother?
I was going to say a good semiauto pistol...but Pax beat me to it and did a much better job of it. The biggest factor is the kid factor. It's nearly impossible to keep a long gun ready to use but out of reach if the kids at the same time. And I've seen so many smaller women struggle with DA revolvers. I winced at my CCW class when the instructor recommended the 70 yo lady with the Judge cock it before firing because she didn't have the hand strength to pull the trigger. Someone did a very poor job finding her a suitable SD gun.
