The Glock is the second encountered pistol in the game. Though it is the weakest pistol per shot than the Beretta and the P228, it boasts the highest magazine size of 20 rounds. It also has a secondary fire that allows it to fire bullets automatically in a rapid succession, and can empty a magazine into your foes in seconds. However, it will become difficult to control and burns through ammunition quickly, so it's recommended to fire in small bursts.

The Glock is placed in weapon slot 2, but can't be picked up if the player already has a existing pistol like the Beretta or the P228. The player must swap out their current pistol if they want to pick up the Glock.
