Been trying to get this Raider working for a while now and can't get it to function reliably with the suppressor. Details on the build, then 2 questions:

• Slide: Full Size P320
• Chassis: Stock + Apex Forward Set Trigger Bar Kit w/ Flat-Faced Action Enhancement Trigger
• Suppressor: Hux Flow 9K w/ booster
• Recoil Spring Assembly: GrayGuns Custom Fat Stainless Steel Guide Rod w/ 14lb Recoil Spring (stock captured spring had same issue)
• Barrel: Faxon Match Series Full Size w/ Patented Flame Fluting, 416-R Stainless, QPQ Nitride, Threaded
• Mags: Sig Sauer P320-M17 9mm 21-Round Extended
• Ammo: 124 and 115gr Range

Question 1: Getting consistent (1 - 3 per mag and mag independent) failure to eject spent cases (see picture 2). Besides going with a lower power recoil spring (~12lbs ?) what else should I be considering to fix the issue?

Question 2: Any tips to prevent the Hux Flow 9K from backing off the barrel? I know with a Direct thread it's going to back off eventually but my comes loose after 2-3 mags.
