Pressure or large firing pin hole?

I just started loading for 9mm but load a lot for rifles. I found a good deal on some Lovex d032-03. Its supposed to be a very versatile (but fast) 9mm powder for all bullet weights. I grabbed some 147gr Everglades bullets and looked up some data. Lovex had load data for everything except 147 (115gr - 153gr). I picked 3.1gr which is on the bottom end of the 153gr range (2.9 - 3.4gr) and loaded at the recommended 1.125" length.

 

They shot great out of my 9mm PCC and showed no pressure signs but the primers seemed to be pretty cratered out of my g45.

I am a noob to pistol pressure signs, but my gut says pressure.  Thoughts on these primers?

I found these just today when I was researching before my post.  I would like to work my way up a bit, but not sure how to know when is too much.  Using rifles, I have ejector marks and bolt lift too.  

 

Any suggestions?
