The main upside of the minigun is it has very fast rate of fire, so you can leave it turned off until you've used all but a couple cannon shots and then quickly finish off the enemy with minigun shots before you take much more damage. Bandits have negative evasion so if you have a +10% pirate cannon it will usually only take 20 or so minigun shots to get a kill. At that rate of expenditure even bandit cars are a pretty viable way to find craft weapons and ammo.

Though I do think I'd rather just hope for a magma cannon, rotogun, or pogrom LMG to appear than spend all that research on the bird. Getting some extra early HMGs and couriers is nice, but not THAT nice.

The cannon sucks ass so even with 2 of them you're not going to shoot much down, but buying cannonballs is already in the game. Besides you don't get a craft with 2 hand weapons until angry bird IIRC.
