Did you clean it before shooting, or just oil it?

How many rounds at this point?

I would give it a good clean and lube. If you haven't cleaned it the stuff they put on from the factory is pretty nasty, kind of gummy. Even still, it's going to break in for the first 100-200. If you clean it after 200ish rounds and it's still having an issue then I would start to wonder.

Make sure you're gripping tightly and not limp wristing, and not riding the slide with any part of your hand or fingers/thumb.

The dirtiness is the down side of the Porting...but if you didn't clean it first, you may find the visit to the range after cleaning it's a little easier to clean the next time, the stuff from the factory, I think grabs the dirt more.
