100,000s of dead enemy combatants dispatched by the 1911 is pure fantasy. But it is funny to read the overblown sentiment.
Most casualties in war are caused by artillery, bombs, motars, missiles, crew served weapons, and then small arms. Of those, the rifle in it's various forms does the majority of the work under 200 yards. Pistols, not so much. Very close range last ditch defensive weapons used by those at command level who didn't see the situation at it's fullest. Oops.
If you need to use a pistol in combat, you screwed up and didn't have your troops in the right place at the right time. And that led to having combat pistols with twice the ammo and a double action trigger, as an attempt to make up for the weak tactics. You get to shoot a few more before the hordes overwhelm you. Ask Custer if it would have made any difference.
Why 1911 on the street for self defense, well, at present, it answers the needs specifically, where a duty gun designed and built for combat is excessive.
Most armed encounters with gunfire average three shots. 8 is enough, and another magazine gets you another 7. If 15 can't do it, you should be fighting to retrieve your rifle or just trying to get away. You don't need to confront in a lot of situations. Having over 36 rounds may not make a difference, accurate shot placement can.
Being relieved of the big grips needed for double stack mags, the gun carries more easily, and therefore will be more likely on you when needed. It's been shown over and over, a large heavy gun isn't preferred in daily carry.
You can get 1911's in alloy frames, with shorter barrels, and in alternate calibers. That can easily equal the variety of chopped duty guns with double stack mags with only 10 rounds in them - which is the alternate in CCW use. More a choice of Brand than capacity or ballistics.
The 1911 has a single action trigger that can be much shorter and a tad lighter. In older adult males and many women, long action cocking trigger pulls from striker fired guns are difficult. To those suffering carpal tunnel, it can literally be life and death. Compare the trigger pull of a first generation LCP vs almost any SA gun by using your little finger. For some of us, that amount of ability may be all there is. Again, like it or not, it comes down to either shoot the SA 1911 or not shoot at all.
Since it is SA, it has a safety - or two - and that means it can be carried with more assurance of reducing ND's than a gun the must keep the trigger guard covered no matter what. Safe action triggers, or long pull SA guns like the LCP require a holster to protect the trigger because anything that comes in contact with it could set it off. A SA trigger with safety, not so much, and in the dire circumstances that the gun is needed, practice is still important either way.
That's why some of us carry an alloy frame 3" gun with 7 round magazines loade with 9mm. It's not all about it being a full sized issue 1911, any more than insisting you only carry a Glock 40 or stay on the porch. Plenty of G26 owners would disagree.
That's why the P938 sells as a 1911 variant, as well as the Pony, Solo, Ultra, etc. They are "1911's" too. It's a type of gun defined by it's controls and action, much less than by a brand name or size.
the width, or lack thereof is also excellent for concealment.
