Recently purchased a Glock 17 Gen 4. Reading GT I am noticing that certain parts w/the trigger assembly are not the same as in the gen G-17/34/19. I have is the past ordered & replaced this previous models trigger assemblies w/after market kits. But w/the new Gen 4, the trigger pull feels much shorter. Two questions: 1) Does anyone know who has an aftermarket kit to keep the pull length the same but lighter? Or 2) will the .25 cent trigger job be the way to go w/the new Gen 4?
