I let my sister in law fire my twelve gauge one time and she spun around in a full circle with the thing. Fortunate enough for myself, my brother and her brother, it was a single shot weapon. If it had been an auto, she'd have likely killed all three of us.
I'm talking a grown woman with some excessive weight issues. After seeing that episode, I would never in my right mind place an automatic weapon in the hands of any female I had not seen firing the weapon properly beforehand.
