Gun UMP45 Viper for GTA IV.
UMP 45 is a universal submachine gun, developed by the German company Heckler & Koch in the 1990s, in addition to the family of submachine guns, HK MP5.
By default, the model replaces the MP5, however, because of our proprietary autoinstaller mods for GTA IV, you can set this model to any other in the game! To download the mod from the link below.
