Gunerang

root@tediore-db:~$ cat description.txt

A legendary Tediore pistol whose real power comes from its reload throw rather than its basic gunfire. Instead of exploding immediately, the thrown weapon loops back like a boomerang and can hit much harder than a normal Tediore chuck, though the delayed return makes it awkward to time in open space.

It detonates once it has traveled back as far as it flew out, so if you stand still and it hits nothing, it can explode on you. At maximum range it hooks left or right before returning, and it only seeks targets on the way back, which limits its effective range. It can also lock onto destructible objects and even airborne rockets. It always spawns with a fixed sight and is excellent for the High-Flying Hurler challenge on flying targets.
