While I’m not doubting any of the stories here I can only relate my own experiences. In one gunfight I did shoot through the front windshield of an old Dodge using my Colt DS loaded w/ high velocity 158 grain lead round nose. In one other instance, using my issued 4” Model 15 loaded w/the +P 158 grain hollow point, I dropped a suspect who was holding a hostage at knife point. I never had to shoot through a car door but did work one case where officers did shoot through a car door using their issued Glock 23 but cannot recall what round was used beyond a hollowpoint.
