Here we go again, my gun is better than yours and no decent elite superman would ever use a gun that the common peasant would. Why would I carry a Glock that same weapon your typical flat foot beat cop would carry when I am Navy Seal, Delta, or some other fantasy Hollywood superhero. Well to answer that question heres what Glock can do.
Mass issue - I can take twenty Glocks, break them down to the smallest piece, through all the parts in a plastic bag, shake it up, put all the guns together with mismatched parts and they will all work. And on top of this I can do all this in under 20 minutes. That means simple fix.
Reliability - I have carried Glocks through rivers, lakes, and in the Ocean (ocean has to do with sea kaiak adventure, just learning) . A moment of stupidity (no sleep for several days) caused me to leave one on a tire and get it ran over by a Suburban, other than a few scuffs still works perfect. I pull the trigger and it goes bang, EVERY time.
Super magazines - Yes at $15 a pop, now $19 for LE, you can bounce them off cement, through them, kick them, and just plain don't take care of them, and they work and work and work. And when just as all mags fail, you toss them and get another for only $19.
Super tough finish - I have a Glock, not as beautiful as some of the closet queens we see, it has been used, and carried, dropped (yes it happens), and as said before ran over, and just plain neglected at times, and not one ounce of rust to be found anywhere. Sure the parkerizing that makes it look all black and new is wearing off over the tenifer finish yet it is still protected by that super hard finish.
Really good customer service - lose a little part, need some new spring cups, striker spring etc., call factory rep on cell phone, parts dropped shipped, in gun next day. Without argument there customer service to law enforcement is better than any other company I have worked with.
Cost - no, just cause it is the least expensive, does not always make things crap. If you believe this you are a car salesman's dream. Why do so many law enforcement agencies cary them, well when working with tax dollars, why not buy something that works for less, so you don't look like an idiot having to replace everything a year down the road. Cause you know someone is going to say, Why didn't we just get Glocks? You can also get officers armorer certified in one day.
Simplicity - key to survival, pull gun from holster, aim, pull trigger. Yes I know this does not include, clear front sight picture, proper sight alignment and smooth trigger press, although that applies to every handgun.
Great trigger - yes it acts like a 2 stage with take up, although it is no double to single like you get in a lot of other combat handguns. The first trigger pull is the same as the last. And one thing I can say, if you think the trigger sucks on a Glock, then learn trigger reset so you are using it proper, before you past judgement.
I know some self made fantasy football elitist always steer clear of the common mans gun, in fear they may be mistaken for common. Although I can say without a doubt, I own Sig, HK, Colt, Smith, CZ, Beretta, and I carry a Glock by choice. Need we say more.
