What is the significance of having the green shot indicating laser remain on while the trigger is fully pressed?

This is a key feature of the SIRT Training Pistol, since when the trigger is fully depressed the shooter’s trigger mechanics can be more properly evaluated when the laser remains on. Our flash visual memory works extremely well at having awareness of the first blurry impulse of the laser while maintaining a front sight focus, and it can easily identify any comet tail-like sweeps of the laser thereafter. Therefore, we can see when the laser remains a fairly tight dot on the target, and this means the shooter is exhibiting good trigger control. When the laser shows an undesirable sweeping action, for example right to left, this generally indicates a trigger mechanic issue.
