re: Shooting through a car door. From inside.

It depends on where it goes through the door. If it hits the frame of window mechanism then it probably won't make it through. If it just hits the door skin, it will barely slow down or distort. If she shoots the window, it will likely make a mess with glass going everywhere since that is safety class and it is designed to break into a zillion pieces at impact.

I recently did some training where we shot through a car windshield from inside the car using a .40 and it had no effect what so ever. I was surprised. It shot straight and true.
