It has 4 and each time you shoot, you must reload. I would say that this addon is effective to finish off your target when it has already taken damage. It is capable of killing enemy with one hit, but it's not easy to pull out.

Engineer ammo packs can be used to resupply your ammo. Also remember that these underbarrel things makes it slower to swap into your main gun, but when you're already shooting with your main gun, and want to change your weapon for this shotgun, the swapping penalty is not there, as it's a weapon addon.
