In the F.A.Q or Handi Basics it talks about pulling the trigger completely through or all the way back. Is this done to prevent light primer hits only? Or is does it have something to do with improving accuracy? If it improves accuracy, please explain how/why. Im also a NOOB, so if you start throwing out terms like "transfer bars" I won't be able to grasp the concept. By the way whats a transfer bar?
