Any problems suppressing an AA conversion?

[Phylodog]

I'm considering purchasing an Advantage Arms conversion for my 19 and would like to put a suppressor on it. I'm sure others have done this before, are there any issues with this setup?

Cory,

I also want to do the same thing. I have checked out the website and seen where you can get a longer barrel but it wont be threaded. Im sure I can take it to Elmores and have Ray thread it for me. I have that Outback II can and think it would be an awesome set up on my 19.
