The 9mm does not have a gas block. I would bet your barrel is held in by the suppressor assembly. That way you never have a SBR. If the suppressor is off, the barrel is not secured.
On the 300 whisper, if you assembled it with the short barrel and BEFORE you put the can on it, it would be a SBR. I have been trying to figure out how you could do a integral can on a gas operated barrel.
The only way I can think of right now is to have the can start after the gas port and be welded to the barrel.
Remember, if the barrel can be secured during assembly without the can making it 16", it is a SBR. Wouldn't want to chance it with the ATF.

Red hit most of it but I will add my 2 bits.
The integral 9mm is still held in place using the standard BBL nut and the can is pinned to the barrel so it is not a SBR. As far as the gas port the nice thing about custom makers like SRT is that they will work with you to make what you want. By having a SOT build the firearm you do not run into trouble.
The only thing I could think of that might be an issue or some thing to think about is a 2 piece gas block so that you can remove it for cleaning if needed.
