Yes, I have both the CORE ported PC 9L and the PC 9L. My personal opinion there is some minor benefit, but not a significant amount. I have video shooting each and from the side view of each shooting the same warm 9mm load you can not tell the difference. Looks about the same and you are hard pressed to tell any different. The porting is not the same as running the comp on my CZ when the comp is working with full power loads there is near nothing.
I run the PC 9L in Production division, the PC CORE 9L ported in Carry Optics division, and my CZ in Open Division.
Shoot Straight and Shoot often
