I made it to the range this morning and ran the challenge.
The only pistol used today was my 9mm Shield (my carry pistol).
The 1st target was shot 'cold' (no Warm Up).
The Orange center on that target is 2" in Diameter.
The 2nd pic of three 6" 'Shoot-N-C' targets are as followed:
Left Target was @ 21', All shots were Controlled Pairs. My Followup shots seem to be going Low-Left.
Center Target was a repeat of the Challenge.
Right Target was at 30', mostly single shots, 1sec-2sec intervals.
For reference, on the 6" Shoot-N-C targets, the distance from one number 9 to the other number 9, is 2" across.
If I can do this with a Little ol' Shield, you guys with the bigger artillery should be able to handle this challenge.
