Friday the 13th (1980)
This article currently has one or more unidentified weapons.
The following weapons were used in the film Friday the 13th:
Officer Dorf (Ron Millkie) has a revolver in his holster but never uses it.
During the chase during the climax of the film Alice Hardy (Adrienne King) finds a whole rack of rifles and picks up one. However the ammo seems to be kept in a different place as Alice is unable to find any. Given how the camp is meant to be for kids we can assume that the rifle is chambered for .22 LR.
Camp Crystal Lake has a huge supply of rifles presumably for a rifle training program, but none are seen enough for a positive ID.
