I installed the OEM Glock 3.5 trigger connector last week, and just got back from its first test session at the range. I was surprised at how much more accurate I was able to shoot with it. The lighter pull makes it way easier to "surprise" yourself, which as we all know really helps no eliminate flinching when firing. The trigger is smoother...same take-up but with less pull needed, and on my gun the break is as crisp as it was before the 3.5.
