Dossier
The compact SMG is not the most dramatic weapon in the arsenal. It does not have the magazine capacity of a LMG or the precision of a carbine. What it has is a usable accuracy profile at ranges the Micro SMG cannot handle and a form factor that fits inside clothing.
For operators who need something between a pistol and a full carbine, and who need to move through environments where visible long arms attract immediate attention, this fills the gap. Vice City is full of those environments.
It is standard across Vice County for mid-level criminal operations. Not the weapon of choice for a full firefight, but functional enough to start one and hold it until something larger arrives.
