"Alright you primitive screw-heads, listen up. See this? This is my boomstick! It's a 12-gauge double-barreled Remington. S-Mart's top of the line. You can find this in the sporting goods department. That's right, this sweet baby was made in Grand Rapids, Michigan; retails for about one hundred nine, ninety-five. It's got a walnut stock, cobalt blue steel, and a hair trigger. That's right, shop smart, shop S-Mart!"
in Evil dead 1, the gun was a savage (i think) single shot in 12 gauge, and the gun magically grew another barrel inbetween movies.
