I finished today's practice with the very hosey classifier
CM 99-23 Front Sight. Two strings of 2-2-2 on three open metric targets at 7 yds. The targets are 7.5' apart so the transitions are wide. I also shot a run with my carry gun (CZ P-07 Prograde). All the times were very close (around 2.4s for string 1 and 2.0-2.2s for string 2) because that's how I was shooting it. Here are the results:
Shadow2: -3C 12.4 HF (96%)
Shadow2: -4C, 12.06 HF (94%)
P-07: -1C, 12.5 HF (97.4%)
This was a WTF for me, and I didn't expect it. But in hindsight it kind of makes sense. I felt like it was easier to stop the very light P-07 on target during a wide transition, and the turn-and-draw felt faster/more precise. The recoil impulses of the two guns feel very similar despite the weight difference because I'm very comfortable with them both. At only 7yds I'm shooting entirely target focus.
Of course my best run was the last one, and it could have just been that. However, it does seem clear that my light compact carry gun isn't much of a disadvantage at this type of shooting.
