Have any of you run your TiRant 45 on a 9mm host?

I got the 1/2x28 piston and threaded barrel for my full size M&P VTAC 9mm. It refuses to cycle at all on factory 115gr ammo. Maybe 10-20% stove pipe, the other 80-90% don't even cycle back far enough to stove pipe, the empty brass just stays in the chamber and requires a manual cycle.

Does the booster spring need to be replaced? Does it need heaftier ammo? Does the gun need a weaker recoil spring? Does it just need more break in (suppressor is brand new, gun is well broken in)? Will it not work at all? I was under the impression the TiRant45 should still work on 9mm.

Let me know your thoughts and experiences.
