Weyland Corp
USCSS Prometheus crew

A semi-automatic pistol was manufactured by Weyland Corp[1] sometime around 2091.

Members of the USCSS Prometheus' crew notably carried the pistol for self-defense during the exploration of LV-223 in 2093.


The pistol had anatomical grips and a vibration-absorbing plastic sleeve around the barrel, increasing the pistol's accuracy. Although lacking a front sight, the pistol had fully adjustable rear sights. The pistol has a blued finish and an orange Weyland Corp logo located on the left-hand side of the pistol. Like the shotgun used by the Prometheus crew, the pistol had a blue muzzle flash.


The pistols were notably carried by the mercenaries aboard the USCSS Prometheus during the vessel's exploration of LV-223 during 2093-2094. However, the only time the weapons were fired was when Fifield, mutated by Chemical A0-3959X.91 – 15, began running rampant and killing crew members inside the ship's hangar. However, the weapons seemed to have little to no effect on the mutant Fifield.

Behind the ScenesEdit

The pistols are likely supposed to be the "automatic pistols" carried by the crew of the ship in Jon Spaihts' original script for Prometheus, titled Alien: Engineers.[2]

Walther GSP Expert

A .22 Walther GSP Expert.[3]

The pistol props used in Prometheus were based on the Walther GSP Expert, likely chambered in .32 S&W Long; the .32 caliber model is generally identified with the extended magazine and blue finish seen in the film.[4] Owing to the pistol's already unusual appearance, few modifications were actually made to the weapons for the film; the magazines were painted orange, the Weyland Corp logo was added to the left-hand side of the body (also in orange) and the pistols' front sights were removed. It seems that at least two props were constructed for the film, as that is how many are seen on-screen at once, but what exactly what became of the them after the filming of Prometheus is unknown.


The unaltered muzzle flash seen in the trailer.

The pistols' muzzle flash was digitally altered to blue in post-production, implying they are some form of energy-based weapon. However, the decision to alter the pistols's muzzle flash to blue seems to have been made sometime after the debut trailer for the film was released as, in the trailer, the pistols' muzzle flash is still unaltered (orange). Another reason that the muzzle flashes were unaltered in the trailer could have also been that all of the film's editing was not finished when the trailer was released or that, as the scene seen in the trailer was cut from the final film (see Prometheus deleted scenes), editing the muzzle flashes was unnecessary, but they still decided to use in the trailer.
