“hold the gun by pulling backward with my right hand, while pushing forward with my left.”
She reports it backwards if she is right-hand dominant (which she says earlier).
In the Weaver, you push forward with the dominant hand and pull back with the supporting hand.
That sounds backwards to me too. Dominant hand (or the hand that goes with the dominant eye, if you’re unlucky) locked forward, non-dominant hand pulling back. (Co-workers looking at me funny.)
