Messing with the trigger is one of the two best ways to negatively impact reliability, in my experience. For a carry gun, personally I would not touch it.
For competition (IDPA, etc), I would make the case that the Glock trigger is pretty much fine as-is also. My carry gun is a G19, comp gun is a G34, both have 100% stock triggers. Before making a change to your gun, IMO you should have a specific result in mind, and be able to state to yourself how making this gear change is going to help you affect that result. If you can do that, then great. If not, I would be hesitant to do something that will be a reliability trade off if the goal is not clearly understood. A single malfunction will likely cost more time than any gear change will save. Just something to think about... I think that side of the coin is not given enough consideration by many.
