Got out to the range this morning to take some slo-mo video of various G19 configurations. Most shots were Norma 124FMJ. I shot “strings” of 1/2/3/4/5 rounds as fast as the dot settled. So fire 1, pause, fire 2, pause, fire 3, pause, fire 4, pause, fire 5. For reference, the black lines on the USPSA target are 1” apart.

Non ported barrel w Gen 3 stock recoil spring v Lucky 7 ported barrel with 15lb recoil spring.
Non ported barrel w Gen 3 stock recoil spring v Radian Ramjet/Afterburner w Gen 4 stock recoil spring
Non ported barrel w Gen 3 stock recoil spring v Radian Ramjet/Afterburner w 15lb recoil spring
Non ported barrel w Gen 3 stock recoil spring v stock G19.5
Lucky 7 w 15lb spring v Ramjet/Afterburner w 15lb spring
And last, I ran 5 rds of 124 +P Gold Dots through the Lucky 7 and Ramjet/Afterburner 15lb recoil spring uppers.
Completely unscientific, but to me, the Lucky 7s were the hands down winner between the 7s and the Ramjet/Afterburner.
Reference target @5 yards.
