The Bren Ten... is it a "grail gun" or a "gutter gun"? On this week's episode of "Weekend with Ken Hackathorn", we discuss the Dornaus & Dixon Enterprises Inc. Bren Ten, 10mm Automatic Pistol. The gun, famous for its praise by Jeff Cooper and screen time on Miami Vice, was only made for a few years in the 19080s before the company went under. For many, these RARE 10mm Autos are "grail guns"... but are they worth the hype?
