Let me first off saying I'm no expert by no means. I had the regular shield and I recently bought the pc shield. In my opinion Anyone who wants to put a apex trigger on it is crazy lol. The trigger on this gun is amazing. The ported barrell gave me No problems at all. I'm 50 years old and just starting to shoot with both eyes open. Don't laugh please. I shot out at 7 yards and put all them in 6 inch group. I know I can get better with practice. I know that don't sound good as far as my grouping goes but I think it's pretty good for first time shooting with both eyes open and a new gun. The gun is awesome.

Love my PC 9mm but I wouldn't mind a lighter trigger pull.

The 9c is a little bigger and heavier.

Like I said I had the regular shield and bought the performance center shield and I think the trigger is better and lighter. I like it.
