I'm not totally familiar with short barrel stuff, but I'd suggest running it wide open to assure reliability on ammo, which you had with the premium ammo. If it locks back on premium ammo,  tighten it down until it short cycles in 1/4 turns. When you open it back up to hit the sweep spot where it locks back every time, open it another half round to get reliability in low power cheap ammo. Don't try to make a precision adjustment.If it's still ammo related, you can lighten your buffer to see if that helps. There are different buffer springs out there that may help as well.The last thing I'd do as a last resort is to drill the gas port. I can't imagine it would be undersize although some may have examples of that.</blockquote>
