Just tried a brand new 30-round pmag in the grendel today. I tried it with 3,5,7, and 9 rounds in the pmag and it functioned flawlessly. 7 rounds was the max before the pmag expanded too much. Above that, the pmag would rub going into the mag well. I was able to load 9 rounds into the pmag, but I had to give the magazine a good shove to get it the magwell and seated properly.
As far as feeding and functioning, it worked perfectly at all the various capacities listed above.
