The usual games I participate in last around 30mins to 1hour and I find that my usual loadout of having 5 mid-cap mags, including the one in the gun, with a loaded speedloader will suffice when shooting conservatively. Now I've been pushing my AK into a suppressive fire role and I would switch to having 4 mid-caps on myself and either a hi-cap or a drum mag on the gun. The hi-cap I'm using is a 6L31 quadstack AK mag with around 1000rnds and as for the drum mag is an electric winding RPK-16 with 2000rnd. With me having to push the AK into the suppressive role, I find that I don't even have to sometimes reload the hi-cap/drum mag at all. And when I do, I just dump the hi-cap/drum mag into my backpack and revert to only shooting at what I can see.
