A new female shooter intimidated by guns?
Either the S&W 63 or 617. The 617 will be a little bigger than the 63. Here is the 63 being put through its paces by a new female shooter:
Not trying to be mean, but with a new female shooter intimidated by guns and you wanting to buy her a 38 Special as her first gun, I would gently suggest you are not in a position to teach her to shoot. If she is amenable, enroll her in an all-female class taught by a female instructor to get her started. You'll be miles ahead than if you try to teach her yourself.
