Based on the handgun colloquially known as
cornerblyat, featured in this video:
https://www.youtube.com/watch?v=v4HA4-mZv9AA pistol with a spying endoscope or a similar device attached to it, enabling one to aim and shoot from behind cover without exposing oneself, albeit at a great penalty to precision (a sort of gimmick that will likely be more relevant in Infusion than in Underrail, hence why it's being suggested here).
Could be a unique pistol as well.
