I'm building a g20 for limited too, already did some trigger work, springs, connector and polish + titanium striker and plunger. I don't think the rocket I have on there is as crisp as the zev on my G34 but the reset seems better and its light, could also be slight trigger bar differences. Damn glock triggers seem like you just have to play with them until its how you like it then don't change anything.... Or spend the $ on a good drop in.
