Interesting. I have the PRP kit in mine, along with the striker spring, which I wasn't going to use at first (light strikes concerns). Somebody else confirm this, but I measured the wire diameters of the striker springs and they were both the same, yet the PRP spring had two additional coils. Go figure, right? So I have all the springs in mine now and the trigger breaks at a consistent 5.5 lbs. Perfect for me as a carry gun. I also did lots of polishing on the trigger bar, disconnector, sear, and the striker. Plus a little trigger bar tweaking for best fit. I think it's about as good as it's going to get, but now I'm eyeing that Galloway quick release sear. Sommmmebody stop me... :mrgreen:
