The Winchester Model 1897 Trench Gun was seen in the hands of Peter Vincent in the movie remake of Fright Night.
Peter used this shotgun for most of the end battle with Jerry Dandridge, however when the other Vampires were feeding on him; Charley Brewster took hold of the weapon in order to destroy the floor boards; allowing daylight to destroy or push back any other Vampires.
Behind the Scenes[]
The Winchester Model 1897 Trench Gun that was designed for Peter had a sawed off stock; as well as a custom made iron sight on it which just so happens to look like a miniaturized crucifix.
The weapon in real life fires the 12-Gauge Shotgun Shell and is in fact a pump action shotgun.
