The 9mm pistol is one of the first weapons players pick up in Half-Life, Valve's landmark first-person shooter released in 1998, and its distinctive firing sound has stayed with the game ever since. Because Garry's Mod reuses Half-Life assets, the same crack became easy to capture and share, turning up in countless gameplay videos, machinimas and soundboards. Its short length and instantly recognisable retro tone keep it popular for creators who want a classic shooter effect without the weight of a modern, cinematic gunshot.
