Senior mob guys never carry, and underlings seldom carry, simply because if they did, the cops could roust them on weapons charges, and get a slam-dunk, multi-year conviction withouth having to go through a racketeering or RICO procedure. Those guys know law enforcement is watching them day and night. Also: you probably read about all the mob busts. How many times (if any) have you read about someone being charged with illegal possession of a firearm?


Mob guys have caches of weapons (or know where to get them) when they have a planned use (a hit) or a bodyguard detail. Otherwise: no.
