I would post this in gear but its a but more specific to PCC's.

Anybody know of a good 9mm subgun chest rig? I know I could set up a universal Molle but I'd like to buy one already dedicated to the Uzi/9mm ar/Glock 18 style mags.

Check out blue force gear.

I use a blue force gear rig in coyote. It is awsome.

US Grunt Gear

Check with US Grunt Gear. I have heard good things about them and they have a 9mm SMG chest rig that should fit the bill.

HSGI extended pistol TACOs let you build your own, if you're into that sort of thing.

Anyone have any issues with Grunt Gear?  I ordered a chest rig from them a month ago and still haven't seen it or heard anything from them.

Same here.

I emailed them earlier this week and they said it was in production and would ship soon.  Who knows what that means and I didn't know it wasn't in stock when I ordered it.

It did finally ship today.  Took about 5 weeks from when I ordered it.

Edit: It showed up today!  It's made very well and is very sturdy.  The mag pouches are semi rigid and preformed so they stay opened up when empty. The mags fit perfectly into them.  It's very light setup with a lot of adjustability, it has some light padding between the mags and your body.  The should straps aren't padded, but they are still pretty comfortable since they are pretty wide and even with 6 mags it's not too heavy.  Overall it's a very nice piece of gear, the finish and construction is top notch, it's definitely worth the wait if you don't need it immediately.

Nice looking rig.
