Had much better results with the Shield with the DCAEK, it is definitely me pulling the shots now, some dead on with some fliers low left, which is now consistent on all my weapons. I'm over thinking it now. I had my son shoot it and both he was good out to 15yds.

I tried each of the suggestions, thanks to all.

Now every time I get a sight picture I think "don't shoot low left, don't shoot low left", so naturally I shoot low left. Great.
