"Your default weapon in most situations. The 9mm pistol may not be very exciting, but it's dependable and easy to use".
The 9mm pistol bears a striking resemblance to the Beretta M92. Unlike the Beretta, the 9mm pistol holds ten rounds in the magazine rather than fifteen. The 9mm pistol has a decent rate of semi-automatic fire and decent firepower, allowing the shooter to taken out several enemies with a single magazine in quick succession. The quick reload also aids the shooter when facing groups of enemies. It boasts a larger magazine and faster rate of fire than both the Magnum and the Revolver, but falls short of both in terms of raw stopping power.
