Please add the sten gun:
9mm smg, single or burst fire, not a really awesome det rate (they were made cheap and fast). Ive found skins for them (see below), even some with built-in (fixed) silencers.
A small confession: I mostly want a 9mm smg to burn off the million or so rounds ive taken off of raiders. Its just too damned many to get rid of. (Id rather the could be sci'ed for gunpowder/met parts, but take what I can get!)
Thank you.
