Do you get artificially faster splits in controlled pairs (double taps) with the SIRT Pistol?

No, at least not if you have a correct grip. We have filmed high-speed video (120 frames per second) of rapid consecutive shots on a single target, such as the bill drill, and the amount of time where the gun does not move between shots is significant. In other words, the slide reciprocates back and forth and dampens down in the hands for less than 5/100s of a second. A fairly fast split with a striker fired gun is 15/100s of a second, and some individuals with single action guns, such as a 1911, can get down to 10/100s of a second. However, there is still a large amount of downtime when the gun is doing nothing after firing, and a limiting factor is repositioning the trigger to the reset and pressing the trigger finger to the flesh of the hand between the thumb and trigger finger to fire the follow-up shot.
