If you leave the canister in the mag, it will eventually run out through minor seepage. Of course, you'll probably blow a seal before that happens.
I think those guns are shooting about 280 out of the box, given that they're C02 powered.
FYI, I saw one of those where the front of the pistol literally snapped off. I would speculate that the parts aren't really manufactured with tolerances required for the cold pressures of C02. So beware rapid firing.
