Didn't work for my p365 - Tyrant CNC T-Comp Sig Sauer P320 Compensator

Purchased this item with great anticipation and excitement. Installed on my P365 that had been previously zeroed with my red dot optic. I was deeply disappointed when I discovered that having this compensator on my P365 cause the shots to vary off by a range of 3-9 inches when shooting a target of 35 feet. Yes, I went through several elimination steps/process to find out what was causing the strike of the rounds to go off zero. After over an hour of going through the process of elimination, it became clear that the compensator was the cause of the variance of the rounds hitting sporadically 3-9 inches off the target. It didn't work for me.
