Nine can puncture car doors and glass. Heck, a sharp knife can easily puncture car steel these days.

But .40S&W, due to heavier bullet weights, more kinetic energy/momentum can bust through heavy bone and other barriers better than lighter weight 9mm can. 40 is also likely a better choice for defense against potentially deadly animals.
