Some guys like to jump at any excuse to bash Glocks, don't worry about it. Personally, I've found room for improvement in the triggers of every pistol I've ever owned, Glocks are no exception or specialty there.
One thing I've found over the years with Glocks is the trigger feel can vary a lot, and each individual gun may need different tweaks to get the trigger feel I like. As a result, no two Glocks in my safe have the same trigger setup in them, every one is different even though the final result is similar in most of them. With that said, the first place I start with a stock Glock trigger is a factory "-" connector and a gen 3 trigger (for gen 4 pistols). I also like to use some sort of overtravel stop, but YMMV.
