In Grand Theft Auto: Vice City, a large amount of weapons were introduced. There is a wide array of pistols, shotguns, and submachine guns, some of which can be purchased at Ammu-Nation or collected from several locations. The game also features the most melee weapons in any GTA game so far, some of which can be bought at various hardware stores. With the introduction of large number of weapons came along the ability to only carry one weapon of one slot.
Subsequently after the release of the original GTA Vice City for the PlayStation 2, Rockstar dropped the real names of the guns, probably due to trademark reasons likely being approached by Heckler & Koch, the maker of the MP5 and PSG1. Therefore some weapons on the list have two names, the first coming from the original PS2 version while the second coming from subsequent PS2 versions and all subsequent ports (PC, Xbox, iOS, Android, etc.). There are other physical differences to the guns between the original and subsequent versions, including the Ruger/Kruger is shortened and given a black skin, while the PSG1 is now standard with a mock silencer.
The weapon icons are different between the PC/console and iOS/Android versions of GTA Vice City. The latter reuses GTA III's weapon icon style, except with GTA Vice City's blue-pink color scheme. Some weapon icons are recycled and recolored from GTA III. Exceptions include:
