Sucks, will not cycle - Killer Innovations Sig P320 Compensator

I have this specific P320 comp and it will NOT cycle the slide. I have tried time after time, round after round, heavier to lighter loads and NOTHING. I set up a slow motion camera to see what was going on and I can tell that the slide cycles ALMOST all the way but than the spring rod impacts hard against the comp and cause the slide to stop short from completing the full cycle. No matter how heavy the bullet it won't work with EITHER rings that come with the comp. One is for high one is for low compensation, neither worked. Also set screw start if tighten to much will scar the barrel. Total waste of money.
