Estimated difference in split times 9mm vs .40S&W

[BehindBlueI's]

In all fairness your OP was purely based around caliber and split times.

Yeah, thread drift.

To further thread drift, in terms of pure accuracy I shoot a revolver better than anything than a 1911 that I've ever had in my grubby mid-sized mitts. I carried a .357 on duty plainclothes and remain qualified on a 2", 3" and 4" Ruger. I still like to shoot them, but I recognize the timer doesn't lie and I'm just better with the Sigs. One handed manipulation is a PITA with a revolver, too.

I got a couple of inquiries on the drill I mentioned on the last page. Below is what I am speaking about. This drill is the "One Hole Drill in Cadence". Again it is a good way to test various pistols and calibers as you eliminate the split times or keep consistent pace between weapons and calibers, so the variance is the pistol and / or caliber.
