I posted this at Gun Nuts, but I'll cross post it over here and cut out some of the cabbagehead talk that's necessary for a different audience. Here's the important photo:
This is at the 2014 IDPA Nationals. I am pretty clearly touching the trigger while moving the gun towards the target. The gun is below my eye level, but is clear of any obstacles, parts of my body, and is actually pointed at the berm in a safe direction.
Notes: I am not taking the slack out of the trigger in this photo. The entire series, captured at a pretty high shutter speed, shows that the hammer doesn't start to move until the gun is at (or pert near) full extension. Also, I don't stage the trigger during this phase, I move the gun to full extension and then press/pull/slap the trigger, whatever's appropriate for the shot.
Now, I understand that this is all situational, because the point where you touch the trigger could change based on the target/situation. To try and avoid that, I'd ideally want to confine the discussion to a static target engagement in competition and training. I know that I get on the trigger early, I've seen it in enough photos to understand it's absolutely a habit I have. Two questions then: for shooters, do you know when you're getting on the trigger, and for trainers, when do you teach your students it's appropriate to start touching the trigger?
