Related to my previous post with the comped G17 under NVGs, I figured I'd test for myself how much the compensator was affecting my recoil with a G19 and G17. The Texas Black Rifle Co Micro Comp lends itself to being able to easily go on and off at will, so we shot some slow-mo of each setup to compare where the muzzle was going while firing at maximum speed.
These were just 10-rd mags shot at the beginning of a casual range trip, not a serious shakedown after rehearsing a bunch and burning it down at lightning speed - I'm not that fast and don't have monster grip strength or anything.
