I just had an odd sort of lightbulb moment at the range.
I've been struggling lately with a somewhat erratic trigger press during live fire. Everything will be fine, then my groups will just suddenly fall apart, showing classic low left hits caused by trigger jerk.
Then something funny happened.
As I would press the trigger, I'd visualize the trigger acting on the internals of the gun. The trigger bar coming back, pushing on the sear as it tips... tips... tips... BANG. Suddenly my rounds are going to my exact point of aim, every time.
The interesting thing is that, as I visualized it, I could start to feel the individual parts acting on each other, and it made it massively easier for me to maintain a constant press through to ignition. It took the press from a black box that I was simply feeding input to and made it into a concrete process that my brain could easily understand.
At any rate, I figured I've stumbled on an interesting trick that I'd share. Goes to show how much of shooting is mental.
