I have seen other videos that teach using a down angle aim in case of a pass thru. The shot is placed in the hip/groin area and the bullets hit the ground behind the attacker.
I had a slide grab my glove once and it cracked the slide as it jamed into the rails. I should have known better because the gun would nip the web of my bare hand most of the time. A PPK clone.
Even if you have a jam you still get a shot off. Make the first shot count. …. you can clear the gun after the attacker is down.
