Handguns are one-handed weapons that are used as sidearms. These are the last resort weapons if their primary counterparts have ran out of ammo or are otherwise ineffective for the task. In SC, there are four handguns to select.
Beretta M9 9mm Pistol- the most accurate but the weakest in SC, which has a magazine capacity of 17 rounds. This is primarily used to deal with enemies that are outside of the SMG's effective range, or where fully automatic fire of the SMG is too wasteful of ammunition for the task.
Revolver- a powerful handgun, it has the smallest clip size, but it carries powerful .357 magnum bullets. This is best used to take down enemies at long range or around difficult corners to avoid engaging them directly.
Uzi- a 9mm Parabellum machine pistol that has a generous magazine capacity of 32 rounds, and it has a high rate of fire. If the user is a donator, these become golden, giving more damage. These can be dual wielded for more firepower.
Desert Eagle- a powerful pistol, like the Mag, it packs .357 magnum bullets, but another round in the clip, and is equipped with a laser sight to be deployed for accurate, precise shooting.
