I have tried a lot of triggers in Glocks. Apex, Agency, Overwatch and I have both the Zev Fulcrum and Zev’s Pro flat faced.
The confusing part about “flat faced” is understanding what they are referring to. Flat can be from top to bottom of trigger or from side to side or both.
A Glock trigger is curved top to bottom and rounded side to side. The Zev Fulcrum is curved from top to bottom but flat side to side.
The Pro “flat faced” is straight top to bottom and flat side to side. The Pro “curved” is curved top to bottom but still flat side to side.
I definitely prefer the Zev Fulcrum trigger. The second closest would be the Overwatch - I’m not sure exactly where the difference in these triggers are - but I clearly prefer the Zev over the Overwatch.
As far as curve vs flat. I find the curve top to bottom is what I’m used to a trigger being/feeling like. I don’t shoot as well with the flat top to bottom triggers.
The flat side to side, does make a difference. I find it to be more forgiving of little errors
All of that is to be respectful and answer the question asked. I still believe that changing to a lighter trigger early on is detrimental to development as a good shooter. The triggers cover up technique problems and then the shooter plateaus and doesn’t become as good as they could be. But, everyone has the right to choose.
Maybe consider switching out to the factory trigger (or even a heavier trigger) for practice and only use the aftermarket for competition. The heavier trigger will expose any technique problems you might have.
FWIW - I only use factory triggers in self defense guns. The aftermarket are only on a couple of guns used for competitions.
