Well, apparently that little bit of overhang was the entire problem. Took the gun out today to do some chrono shots (and test the gas system of course), and it locked open on the empty mag at 2 turns out. I added half a turn and left it there. Worked flawlessly from then on. I put a full magazine in, and didn't have a single failure to cycle, either. SUPER happy with how the gun is running now! I put a bipod on it as well so I could dial in the scope (yes, a bipod on a pistol lol...hopefully that's not illegal as I was ONLY USING IT FOR SIGHTING IN THE GUN), and ended up with about 2moa accuracy. I'm figuring the poorish accuracy is a combination of me and the Wolf 100g ammo, rather than any issue with the gun. Velocity was lower than I expected from all the reading I've done, running from 2,380fps to 2,440fps over 10 or so shots. From the few short barrel threads I've seen for Grendels...I was expecting more consistently closer to 2500fps. Again though...I'm sure Wolf ammo isn't exactly premium lol. I need to pick up more Hornady SST and see how it runs that.
Anyway, here's a short video of a handful of shots. Still getting used to the no shouldering thing with this gun.

All in all I'm super pleased. Couldn't ask for more to be honest. Now I just need to grow into it
