yeah, but they won't DO that. However if it were to happen, just how much more effective would a 45 JHP be? Everything is shot placement anyway. Could issue 22LRs and if we could be sure the troops could make the cranio-ocular shot everytime, it'd be fine. That being said, this is as much about troop perception as anything else. As long as the troops have the idea that a 45 will knock a man off his feet or blow his arm off they're gonna want that security blanket. Even if it comes in a FMJ. Because compared side by side, the 45 ball beats the 9mm ball everytime. Face it, in the realm of infantry combat if the bad guys get close enough to use a handgun, something has gone very badly wrong indeed. The possible exception being of course the tight quarters of clearing rooms or caves. Here, a 45 1911 ot better a 45 H&K with ah attached SureFire Gunlight would be superb.
Personally, I like the 357 over the 45.
