"Honestly guys.. is there really any real reason to change the trigger on a dedicated ccw Glock?"
NO, absolutely not. To do so is nothing but utter foolishness and fool-hardyiness.
If you want to treat your Glock like a hobby/plaything, tinker to your heart's content.
If you want to use it as a weapon, to defend your life, stop frackin' around with it and practice, practice, practice with it.
