9mm

9 millimeter, also known as 9mm (Yellow) in the game, is a type of Ammunition in surviv.io. It is also the most common type of ammunition found in the game, though in desert events, it's substituted by .45 ACP.

Info
9mm ammunition was invented in 1898 by Georg Luger, primarily to be used with the Luger pistol, which he invented. In surviv.io, 9mm is used for three Pistols and five SMGs.

Trivia

 * As mentioned above, the 9mm ammunition in-game is based on the 9×19mm Parabellum cartridge, as all 9mm weapons currently in the game fire this round in real life.
