There are a couple of different uses common to the GLock (and all similar pistols), and they are personal, and professional.
A gun for your personal use can be what you like, and can be used and carried the way you like, and are comfortable with.
A gun for professional use often cannot. Generally (and in particular with large depts.) it is what the dept issues/authorizes, only. Holsters too, sometimes. What is fine for the private citizen's personal protection is not always the best thing for police, and vice versa.
And so the NY trigger. Having more people under arms in NYC depts. than the total population of many small towns, NYC saw they had a problem, and choose the heavier trigger as the best solution, for them.
I can easily understand Mas Ayoob favoring the NY trigger, for police. I've also read his opinion favoring the DA auto pistol over the 1911 style, for police use. And, as far as I know, he's fine with the SA auto for military and civilian use.
His reasoning is simple, and elegant IMHO. Police officers often have to hold suspects at gun point. Anything that increases the risk of an AD/ND when holding someone at gunpoint is a poor idea. The usual short light crisp trigger pull of an SA auto (and I'm including GLocks, etc) makes the gun both easier to shoot well, and more likely to have an inadvertent discharge under stress. When A soldier points a gun, the general assumption is that they are the enemy and one shoots them. Police are in a much different situation.
Any individual may be fine with the SA trigger, given competent training and a level of personal dedication to safety. However, when you look at large groups of individuals (and NYC has literally thousands of people armed), you ARE going to have some people who are not as safe as they ought to be.
NYC decided that what was best for them (probably on the basis of cost) was everyone having the heavier triggers in their guns. Quite probably cheaper and actually more effective in reducing the risks than any training program could be.
This doesn't mean its the best solution for you, or I. Only that they thought it was best for them as a dept. I see a big difference there.
It is not bashing GLock (or similar) stating the obvious facts about the way they work. Its not bashing to say that in some situations they will fire when a different pistol would not have. Its a fact, and its true. And it does not make the design unsafe, or inferior, when used correctly.
A different pistol not going off in a given circumstance is a plus for that pistol, only. Not a minus for the GLock pattern guns.
I will repeat that I don't like GLocks. I have also shot some S&W and other guns similar to the GLock, and while I like them a little better than the glock models I'm not in love with any of them, either.
I'm ok with the concepts, I just don't like GLock's execution of it, that's all.
Good? ok. Great? for some people. Perfection? not in my opinion.
