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 am curious how the 7.62x25 would compare to the 5.7x28 loaded with a 40gr Barnes spire-point solid. I think they would give each other a run for their money, and I know for a fact that the 5.7 combo will go through multiple (4 or more) IIA rated vest inserts.
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.
The Barnes bullet is not armor piercing, and anyone can own/load it. Fair is fair.
Cool then! It’ll be really interesting to see how they compare. (Old vs new). I might buy a Tok in a near future, so I should remember this thread and follow up on it.
I won’t buy a 5.7x28, so you will have to compare it some other way.
