Hollowpoints in 9mm, .40 and .45 will all penetrate about 12-15", sometimes a little more. Round nose bullets in 9mm, .40 and .45 will all penetrate through and through a person easily. And check out box of truth's website. They found that through a windshield, the .45 had the least deflection after penetrating the windshield. And no round was stopped by a car door.
I am so sick of these penetration/caliber war threads. Are you lining people up and executing them, Nazi-style? Are you shooting through walls and doors in your defensive scenario? Are you a cop? Do you really, really, really want to be a cop?
