** What is an acceptable grouping size for rapid fire and double tap drills, while practicing at 5, 7, and 10 yards?**

If you are referring to defense shooting, the rational behind "Double tapping" is maximising your chances of hitting your intended target's vital organs. This is best achieved by shooting a spread the size of your hand on the "vital mass/torso" simultaneously or as quickly as possible in order to incapacitate the threat .

A "successful" double tap is therefore the equation of accuracy (with the torso a hand apart), speed and distance .

- If your 2 shots are very tightly grouped you missed the point as you will have hit twice at the part of the body, at worst missing organs, at best the same, and therefore might have missed a vital one, ie : you should have been shooting faster.

- If you come out of the torso, you failed, have been shooting too fast and need to slow a little to recover gun control & accuracy.

As a general rule, assuming you can shoot accurately at a "normal" pace, it will, therefore, be the distance that will dictate the rate of your firing in order to place your 2 shoots.

0>3 meters use the frame of your pistol to aim / shoot as fast as poss ,

3>7 meters aim with the frame & front sight, at tad slower,

7>above, both front & back sight, 2 distinct shots,

I hope the above makes sense to you ??
