You're welcome. There's always the possibility that I'm wrong, too. Wait and see if anyone else with more experience chimes in as I've only owned a few Springfield 1911s.
Ryan got it. There is the V10 porting on the compacts, V12 on the full size, and V16 on the big 6" longslide 45 super. Any of those configs can be ordered through the custom shop, but those are the correlations I have found so far…and I have researched a TON of springfield 1911 configurations…
