Well, that about covers the "9mm vs. .45" discussion.

here's some penetration to further muddy the waters:

DoubleTap 9mm+P from a G17
115gr. Gold Dot JHP @ 1415fps - 12.00" / .70"
124gr. Gold Dot JHP @ 1310fps - 13.25" / .70"
147gr. Gold Dot JHP @ 1125fps - 14.00" / .66"


Oh well, i'm still in the "shot placement" camp.
