Reddit reviews PMI 10 Round Tubes With Lids - 10 Pack

This is my 'setup' right now. It's balanced well and works just fine, though I do take off the air tank to run it as a secondary with a holster.

I would definitely recommend getting this holster -- the one made by Tippmann is utter garbage. This one is adjustable, so it works with most pistols and can fit the TiPX with some work.

12-gram CO2 cartridges fit in shotgun shell loops like a glove. So do 10-round tubes, the best way to reload your magazines as you go.

I use this vest and it fits five extra magazines: two for each of the bottom-forward large pockets, and one in the pocket directly above that with the four shell loops. Those will fit CO2 cartridges perfectly.

A word of warning, though... while this vest works perfectly fine, it's a bitch to clean and I'm starting to regret that I didn't get a MOLLE vest with mag pouches. You can't hold more than five magazines with this vest.

Also, consider getting the FXR carbine-mod when it becomes available next month. And even if you don't like that, the ZetaMag (which is an extended magazine that gives you 20 shots per magazine) is definitely worth a look.
