The Bren Ten...
Was used on Miami Vice the first 2 seasons. In the Pilot it was a SIG P220 carried in a Bianchi vertical shoulder rig. I fell in love with the Bren from a magazine article, and then it was reinforced by the series. I carry mine now everyday in a Miami Classic, and I still love it.
two I would like to get is the revolver Indiana Jones carried in Raider of the Lost Ark, and whatever the heck it was that the lead carried 2 of in The Mummy.
