Dot Torture is a popular accuracy drill that you can use at any speed and keep using to help progress your speed without losing accuracy. Maintaining the balance for this is pretty easy- set your goal for speed around where you can maintain 90-95% accuracy on each stage of the target. Try starting at 3 yds. When you regularly achieve that goal it’s time to either decrease time or increase distance.
It takes 50 rounds to complete the exercises. When you do a good job on the target it looks something like this (which is something I’m using to gauge my accuracy training results- and that target isn’t my work…yet).
Directions are under each dot and 1,2,5 and 8 are stand-alone segments while the rest of the dots function as pairs. There is a great printable target on pistol-training.com you can use to print a couple (preferably on the office printer) and try it out.
Remember that Fast is Fine, but Accuracy is Final. Your personal training goals should reflect this too because you need both but speed without accuracy typically won’t win a fight.
