If I was stuck with ten rounds I would for sure take .40 Smith & Wesson or .45 Auto over 9 millimeter Luger. Thank goodness I live in a free State.Magazine capacity: I understand the tactical advantage of higher capacity magazines. However, I also recall the days when a .45 ACP was THE auto loader to bring to a gunfight. The emphasis was then on one-shot stopping power and the guns had 7 or 8 round magazines. The catch phrase was something like "power, speed, accuracy". Maybe this 10 round thing will bring back a focus on power.
