Perhaps so- I have GG kits in my two P320 X-Fives and those come with a nickel PTFE coated, reprofiled sear, different springs and stops, and a trigger with different leverage points and overtravel adjustment. I think those kits were ~$110 when I got them, and go for ~$150 now (with several finish options on the triggers available).
If you can get most of the benefits- including drop safety- which is the rationale that GG ascribes to various re-engineered parts in particular- for 1/5th the cost of a kit, or about 1/9th the the cost of sending it into GG for the work, then this could be a good thing for users, and a blow to the aftermarket smiths.
But I would personally want to see some test data, to see if this really does maintain safety.
