Fixed firing pin? Out of battery?
I assume this is a PSA upper?
Where did you find this load data? Only published load I can find is for 120gr Gold Dot at 25.3gr. You were at 27.7gr!
Alternative guess:
Over charged by 2.5 grains of powder. Port pressure way over gassed, due to pistol length gas system and over charged ammo. Super rough PSA chamber (I know I have one and had to fix it with a chamber hone) didn't let go of the case in time and the extractor ripped the rim off.
