M3

The M3 is the shotgun you get by default when you start the game. The damage is 120 for a chest shot. The damage is good for a shotgun but it only has an ammo clip of 8 and a ROF of 1.4 per second. Also, the distance is pretty low so you're better off playing it on smaller maps. Overall, it's a pretty default gun, but I wouldn't usually recommend it.
