G-19 Handgun: Dot Sight
The Dot Sight is listed as an upgrade for the G-19 Handgun. The guide places it in the Downtown Upper Walkway room on the second floor, which contains a safe but is not itself a safe room.
Understand this choiceThis reference covers ten named weapon upgrades documented in a Resident Evil 3 weapons guide: parts for the G-19 Handgun, M3 Shotgun, CQBR Assault Rifle, and .44 AE Lightning Hawk. The guide gives locations and progression clues, including safe combinations, keys, puzzle routes, and Nemesis Supply Case events. It identifies which weapon each part belongs to but does not explain how the parts alter performance, so this reference does not infer effects from names such as Extended Magazine or Scope. Steam metadata establishes the released PC game’s identity, not its equipment mechanics. These records describe only what the supplied game-specific guide states; they do not assess effectiveness, provide a complete equipment catalog, or verify details against another source.
