Solemn Lament first appeared in Lobotomy Corporation as E.G.O equipment extracted from the Funeral of the Dead Butterflies abnormality, then returned in Library of Ruina as a usable combat tool. Both games by South Korean studio Project Moon built a cult following for their dark lore and distinctive audio, and clips of signature weapons spread through fan edits, wikis and soundboards. The gunshot remains popular because it is tied to a memorable abnormality and does not sound like a generic stock shot.
About this sound
The Solemn Lament gunshot sound effect from Library of Ruina, the heavy pistol fire from the Funeral of Dead Butterflies E.G.O used for game edits and memes.

That contrast between sudden violence and quiet sorrow is the point, giving a simple trigger pull a heavy, final weight. It lands as both a combat effect and an emotional punctuation mark, instantly sombre and unmistakable to fans.
