eh, im not saying spary and pray is perfered, that just what you got out of it, but it happens, not everyone is trained like others are. others get taken over by adreniline and go into "survival mode" so to speak. also dosent expain why a majority of law enforcement agencies and the military primarily use stuff other than 1911's
They use other guns than 1911s for a number of reasons, some of which are;
1) Cost -- as I said earlier, the 1911 is an old design, originating in an era when labor was cheaper. Most more modern designs use polymer frames, stamped components, cast frames, or other measures designed to reduce cost. The 1911 requires more machining than most more modern pistols.
2) Trigger -- most police departments and militaries want double action triggers. Militaries (apart from elite units) receive very little training time with the pistol, because it's just not a weapon they use much. Even police officers, whose pistol is usually their primary weapon, don't receive near enough training time on it (in my department, we only have to qualify once per year), and this is usually because of budgetary constraints -- ammo costs money. Because of this, and because police chiefs and city attorney's are terrified of liability, most departments shy away from single action triggers, in favor of a double action, which is regarded as more "idiot proof" and less prone to negligent discharges.
3) Magazine capacity -- this really is mostly a non-issue for civilian shooters, and, as statistics show, actually mostly a non-issue for police as well, but... it has to be said that for a pistol which will be carried openly, there's no reason not to have a double stack magazine (except possibly hand size, for some shooters) if you can.
4) NATO standardization -- this is the main reason the U.S. military changed from the M1911 to the Beretta 92.
And there are more reasons, as well, but these are the main ones. But none of these reasons apply to the elite units to which I have previously referred, who can often select any weapon they want, and who do it based on their mission requirements. And they have found that for them the 1911 works better than anything else. Once again, there is no other pistol that has a better trigger, and better ergonomics, and if you have invested the extra time in building your skills, no pistol that you will be able to fire accurate shots with faster than the 1911. Most people don't have this level of skill, and other pistols will serve their needs as well or better. But the guys that do have it, mostly shoot 1911s
