This gun is completely worth it!
It performs as a quick secondary to finish off enemies or to completely wipe their HP in close-range encounters.
If you want to spend some money on a secondary weapon, I recommend you save up battery pallets, buy a 90 day USP, and get this, you won't regret it.
Also has a pretty decent recoil+spread.
You might get some people hating on you for it though.
