From the 1908 patent:
"This invention relates to a device adapted for attachment to fire-arms of various kinds, more especially to shot - guns or hunting rifles, and has for its object to facilitate quick and accurate pointing of the weapon without being obliged to adjust the gun-stock to the shoulder for aiming at birds just rising from the bush or in flight, or at other game.
The invention is based largely upon the fact that the conscious or sub-conscious faculties intuitively enable men to point the index finger directly and accurately at any visible object without bringing the outstretched finger into alinement with or between the eye and the object."
Now, if you have your finger along side the 1911 and press on the take down pivot when you pull the trigger with your middle finger, the slide stop can be displaced and jam the gun with firing.
That's a fact as attested to by the US Army.
The
US Army also says that that aiming method is fast, natural, and accurate, but cautioned against using it with the 1911. That caution appeared in 13 publications issued from 1912 - 1941. http://www.pointshooting.com/1911.htm
I was able to find 13 instances, but am sure there are additional pubs that are now in the dust bin of history that carry that same caution. (Older books and publications are only now becoming available to the public via Google's book project.)
A few years ago, I had two jams using a different pistol that had a slide stop of a similar design.
Due to the design flaw of the slide stop of the beloved 1911, the natural and accurate method of aiming and shooting as described in the 1908 Patent, can't be used with the 1911.
And by the Army's not fixing this minor design fault, those who went and still go in harms way for us, were denied the optional method of natural and accurate shooting at CQ distances.
To those of the mind set that you must always use the sights, NO PROBLEM.
No problem that is, if all gunfights occur in good lighting, and that one has the time and composure to use them.
Also and IMHO, you better have the composure and ability of a professional shootist or SEAL type, because if you are going to be shot and/or killed, there is a 90% chance that that will happen at less than 15 feet.
At that distance there will be little time for proscribed breathing and careful squeezing of the trigger, and REAIMING each shot taken, and etc...which are critical for accurate shooting.
Armed Forces members, Police, and others who do not know how to Point Shoot, will be "on their own" in CQ life threat situations. And according to the literature, the shooting method they will employ, is instinctive shooting.
Not a bad choice given no other, but most likely an ineffectual one, as the acknowledged MISS rate in armed encounters is 80+%.
The only saving grace is that gunfights are rare, and most likely the perp will not know Point Shooting.
So unless one is having very bad day, he/she will not be in a gunfight, and if so, will probably survive anyway.
Sure, there are those who say that you can accurately point a gun by just pointing it at a target, but that is not reality. You can easily prove that to yourself the next time you are at the range. I have tried that, and my results were very poor.
There are several methods of Point Shooting that you can familiarize yourself with. P&S, CAR, FAS, Threat Focus, ....
And none are a bar to the use of the sights, if there is light to see them, you have not lost your near focus ability and/or your fine motor skills, and there is enough time to aim each shot properly.

More info added 2/25:
Just reviewed the Crimson Tracer video. If you don't have one on your gun, your index finger can do the job for you, and for each and every shot, and for shooting from most any position at CQ.
What do you use to assure accurate aiming in situations shown in the video at close but beyond contact distances or at night?
Also, the clip of the guy shooting from the car, looks much like the CAR method as described in an article on my site. I developed it from the CAR training manual and videos. It was approved of by Paul Castle as written.
I haven't tried the under my arm and upside down to shoot backwards method shown in the Crimson Tracer video, and don't plan to.
But, there is a video on my site showing me moving and shooting and hitting the target.
Jack ruby used the index finger to aim and the middle finger on the trigger method, to kill Oswald. See the pic on my site or link to it of Ruby shooting Oswald. Lots of the same pic on the web.
In the references cited in the article on the 1911, mention is made of the French Officer shooting and killing a German Officer using P&S in the late 1880's.
And how about the Chinese Army using it when shooting the broomhandle?
If you are a soldier, you do what you are told to do, at least I did most all of the time.
I didn't carry a pistol.
For a time I carried a grease gun and was told to use the P&S when shooting it from the hip by a Sgt who had been in WWII. Worked back in 54 or 55, and still works today.
See my avatar pic from a night training exercise at the NCO Academy in Munich. I was a Cpl for a time, then a Spec. Note the helmet and arm patch.
As I have stated many threads, would like to see a few videos and pics of Sight Shooting actually being used effectively in a CQ engagement since its been the cat's meow for the past hundred years or so.
But dingy dang, they seem to be rarer than hen's teeth.

Lastly, thanks for your comments and hopefully I have maintained a reasonable sense of decorum.
Best regards.......
PS As to aiming, P&S gets you a fast automatic and correct flash sight picture for each and every shot at CQ: see
