In my experience shooting car doors, the more KE, the better. 357SIG and .40S&W and 124g+P 9mm all did better than the .45ACP and 147gr 9mm I shot at the car door. Same results regarding pine that I shot, FWIW.
With windshields, I think it has been determined that more weight=less deflection. However, using bonded ammo, 9mm-.45ACP seems to do about equal with regard to distance penetrated in gel after the glass.
I went and found it for you.

As noted, it all depends on the barrier. Higher velocity projectiles generally work better against steel, while heavier projectiles tend to offer better performance against windshields.
Well, the ultimate barrier penetration using a handgun, would be with 7.62x25! Good old Tokarev or CZ52 and kevlar helmet is no more. Same goes for car doors, brick walls, many bulletproof vests, etc...

I'm sure it will be tight race, but if we were comparing apples to apples (no armor-piercing ammo, just ordinary FMJ ball), then I have a feeling that 7.62 will still win.
