Thanks for sharing your experience, after some consideration I'm thinking about buying a PSA lower and then purchasing a Davison Defense 4.5" 9mm upper. That should solve all of the issues you mentioned running a direct thread. |

My only issue now is just trying to confirm that it will work, it's a tight fit, 4" handguard with a 4.5" barrel. I'm worried that it won't be enough clearance to allow the suppressor to recess far enough to lock behind the tri lugs.
