The DS-1310 is the fourth shotgun to be unlocked for the Heavy class. The DS-1310 is the first semi-automatic shotgun available, sporting much faster reload than pump-action shotguns, as it reloads via a magazine as opposed to reloading shell-by-shell.
Like other shotguns, the DS-1310 very powerful at close range, and sports a superior fire rate than pump-action shotguns. It also features a unique parabellum magazine that needs to be rotated after every 4 shots. The rotating magazine isn't too much of a hindrance, though it results in a short firing delay after every 4 shots fired which the player will have to keep in mind before engaging in firefirghts.
