Reset the sights today. Counted the number of clicks in total for the vertical and horizontal adjustments, set them to the middle and adjusted them as needed from there. As it was the setting I already had weren't far out anyway.
Getting the overall group sizes smaller, with more shots in the 8-10 range and less in the 6 or worse range. Still heading in the right direction.
Heard today that the new Air Cylinder is at the suppliers. that means I will have a chance to get used to the weight change in the pistol before the National Championships at the end of the month. Unfortunately no sign of the new grip I need.
