Morgan finds the weapon on the corpse of a fallen security guard. On the backside of the Pistol there's a small screen showing the overall number of ammo in the inventory and the magazine. The weapon seems to to use a toggle-lock action, as a portion along the top of its upper frame is seen bending at angle and moving backwards to eject a fired round. During its empty reload, Morgan can be seen pulling a small handle on the side of the pistol in order to cock the action and chamber a new round.
The pistol seems to be a reasonably accurate firearm, with a rather high magazine capacity. To offset these traits, it appears to deal relatively low damage per shot.
