So long as the crown is square to the bore, I should be good to go. The internal diameter of the suppressor's bullet channel is 0.400". Given that the diameter of a 9mm bullet is 0.355", the muzzle would have to be off significantly from square in order for there to be a problem. Now that I think about it, I'm not sure that having the suppressor go all the way to the shoulder would be better. In theory, the shoulder might not be square to the barrel. Fact is though, both the shoulder and muzzle look to be square to the bore. I'll let y'all know what happens.
BTW, I'm not sure that the spacer would work. The part right before the shoulder is not threaded, just like an AR15 barrel. If the inside diameter is threaded throughout, it wouldn't be able to screw all the way to the shoulder.
