This is a generic weapon sound effect rather than a clip taken from a named film, game or recording, and that is part of its appeal. The combination of a single blast and a pump-action reload has long been used in film, television and games to signal danger, authority or a sudden escalation, and the same pairing has become a standard stock effect for creators. On soundboards and in short-form video it is shared as a ready-made impact cue, because listeners recognise the action instantly without needing any context, and it still works as a quick way to raise tension.
