Sounds like a nice set up. I'd keep the 9" barrel---147g ammo will still be sub sonic through the suppressor---when you get it. The problem with the 5" barrel is that you'll never be able to use the hk 3 lug flash hider because you will not be able to get inside the 7" FF rail to put it on---ask me how i know. The 5" doesn't bother me now because my suppressor is on full time. Plus, it makes the overall length shorter with the suppressor. That was part of the reason i cut it down from 10.5" to 5.5". I'd at least keep the 9" on it until you get the suppressor and then see how you like it.
