Get the gangster mug.
Someone who wears an expensively tailored suit and carries an expensive, usually custom weapon or weapons. Usually Italian or Asian, but exceptions do exist. Participates in organized crime, usually related to bootlegging illegal drugs and weapons, but often involved with abuse of women and extortion. M1928 Thompson submachine guns and Peacemakers or M1911 Colt .45s were trademarks of Prohibition-era gangsters, but the TEC-9, MAC10, M9 Beretta, and Glock 17 are the most common weapons on today's streets.
Bonnie and Clyde, Al Capone, Crips, Bloods, etc. are famous gangsters.
