One of the main reasons I included the SHO/WHO work was because of female students. I wanted to make sure they were capable of a) pulling the trigger WHO and b) firing the gun SHO without it flying out of their hand. Neither of those is a given. I've had fails on both of those in classes.
There was a documented incident in Florida where a woman had a snub and had received gunhandling instruction from a local policeman but had never live fired it. Unfortunately, when she had to defend herself, the gun flew out of her hand upon firing the first shot, which didn't hit. IIRC, the incident didn't end well for her.
