The lady is in poor health and we don't know what she is or is not able to do. Someone needs to take some of the suggested guns (whether owned or borrowed) to the lady and she if she can operate them by herself. My son-in-law's father saw a Taurus PT111 my son-in-law had recently bought and said he would like to buy one for himself. However, he is 81 with arthritis and he was unable to move the slide enough operate the pistol. He also cannot operate a revolver (he has several).
