I finally go out to the range to test out the trigger kit- WOW WOW WOW!! I installed all the springs (return spring, trigger block spring, and firing pin spring) and I have about 125 rounds through it flawlessly! Every one went bang, and I have to say, my buddy has a Shield 9mm with the apex kit in it, and the factory trigger, and they feel almost identical as far as trigger pull goes. I like the long takeup, but now it breaks cleanly, has a nice fealt reset, and is just such a nice pistol to shoot now! My accuracy went from about 40% on paper, to about 95% on paper, and most in about a 6" circle at 30 feet at times double tapping pretty rapidly. I was using an 11x18 target, and using the upper half to gauge my point of aim- I was a little left of center, but did pretty well. I am very happy with the kit, and highly recommend it.
