Prepping vs. staging the trigger
I stumbled across some good discussion on trigger control, in particular a thread by Jay Cunningham on dry fire. I believe one of his point (and please Jay, if you're out there, correct me if I'm wrong) was the the proper trigger press is one motion with continuous rearward pressure until the shot breaks and then you want to reset the trigger very quickly during recoil. Contrast this with taking the slack out of the trigger, pausing while you further clean up the sight picture and gun reaches full extension, and then pressing the trigger the rest of the way. The seconds sounds like it has three parts to me - wall, pause, break the shot versus the first which just has one.
So I think of "prepping" as starting the continuous trigger press during the aiming and extension part of the draw while "staging" is just what I described above, a press to the wall, a pause for sight alignment / picture, and then another press to break the shot. It's prepping in that I'm (correctly?) working the trigger, while aiming the gun, and moving it to full extension all at the same time rather than doing one after the other. Staging seems to encourage me to want to "jerk" the trigger or anticipate the shot.
Am I thinking about this correctly? Feedback / thoughts? How do you work a trigger? For reference this is in the context of a Glock trigger.
