An untraceable gun. A staggering majority of violent crimes involving firearms are committed using dumb gats. The mafia & criminals in general are not going to be deterred by gun-control laws, they will be willing and able to procure untraceable arms of their choice and use them to commit crimes irrespective of any laws.

Vinnie: "Drop the dumb gat and take the cannoli wit you."
When someone wants to impress their friends so much they’re willing to do the dumbest shit ever. This decision usually is not at all thought out and comes with severe risk and consequences. A combination of Dumb and Radical.
