When I really try to speed up my splits on controlled pairs, I find I tend to mash the trigger on the second shot. Here's an example: This target has two controlled pairs, at 10 yards, from the holster. Each pair was about 1.7 seconds to first shot, with about 0.30 splits. The first shot is in the center circle, and the second shot is low and left. I saw the front sight on the center of the circle for each shot. When I extend the split times just a little bit, say, to between 0.40 and 0.50 seconds at that distance, I can consistently keep both shots in controlled pairs at ten yards in the center circle. The problem isn't with my first shot; it is always with the second shot. The mash always occurs on the second shot in a controlled pair. Just slowing down is one solution for sure. But I want those fractions of a second. Has anyone here overcome a second-shot mash? Do you have any drills or other practice techniques that might help?
