These guns use a smaller paintball and they are stored in a clip. The CO2 goes into the butt of the gun. Nice tight package, very accurate as well.

Or you can get a gun like this. Regular hopper suck ass. I suggest purchasing a Q loader. They look like this
They hold the paintballs in a closed spiral pattern that runs parallel to the gun. This is much better than a big awkward hopper than could potentially lose you your paintballs. The loader pods are also incredibly easy and fast to swap out, so if you like to go through your rounds you can load up several pods (100 rounds each) and put them on a vest or strap them to yourself.
