Im actively looking for one of these for my son. from what ive seen online, it comes with a super full choke in the gun. Already picked up some Federal TSS 9s. Did you ever pattern the shells with the choke that comes with the gun?
I have, the Mossburg XFull patterns 1 5/8 oz TSS #9 handholds in the upper 250's in the 10" at 40yds with a nice even hunting 15" pattern
it also patterned the Fed HVWT 15g #6's very well
it patterned Fed HVWT 15g #7's OK, but the Trulock choke did better for the #7's
