For a gas gun, you're gonna want at least 5 magazines. One on the gun and four on your body. You can reload on the field but even with a speed loader a gas mag is very slow to top up. You're forcing tiny little BBs into stiff feed lips. It's in theory like a real gun but in practice much more of a hassle.

This is not even touching on needing spare mags for when one springs a leak or has some other issue. I tend to take 10 loaded and gassed mags to a game. I carry a few and leave a few to swap out during a lull. I usually tend to unload a couple of them when I get home at the end of game day but I find that less annoying than having to call myself out because I've run dry or dumped gas.
