The laser stippling is a small step up from factory, Black Box Customs work would be at the top of my list for guys to do work in Canada. Agency Arms is the pinnacle (have their work on a few other Glocks), but in Canada BBC would be my suggestion.
Compared laser stippled vs. Black Box work last week at TacWest in Calgary and they really are worlds apart.
With the G19X the factory sights aren't the plastic garbage factory sights so that may not need any upgrading at all. If I recall correctly they are already night sights.
But yes, all of it is specific to the shooter, you may love the factory trigger - but likely not.
These were the ones we were playing with at SHOT Show this last January and they shot SUPER nice!
