Guys, the 1911 is still the worlds best combat pistol, hands down. The round is big, slow moving and more destructive than any other pistol round used in the military. A drawback is the number of the rounds in the mag. That is that it is less favorable in a spray and pray situation.
But what is the purpose of a hand gun? Close quarters, confined space, face to face personal protection. When given the option, would you not want a round that will stop an attacker or one that makes more noise.
An FBI report that I read a long time ago talked about the new, at the time, 357. A leather clad individual involved in a bank robbery was shot 6 times at fairly close range with the 357 but was not stopped. Bad aim? Who knows, but an agent at the scene stopped the individual with one shot from his 1911.
I carried a full sized 1911 in Vietnam where I served as a Medic. I saw first hand the overwhelming power of that round. Took a man apart with one while protecting a wounded buddy. It is why I carry one every day. Besides, if you have to throw something at someone trying to cause you or your family harm why not use a proven man stopper....the proverbial ashtray if you will. It is why the Marine Corps went back to it.
