Vasquez's Pistol should have been destroyed when Vasquez and Lieutenant Gorman committed suicide with a grenade in the Hadley's Hope air ducts, yet it returns in Aliens: Colonial Marines. What's more, the weapon somehow found its way out of the ducts and back to a room on the lower level of the colony's main operations building.
It is somewhat ironic that Vasquez's Model 39 was replaced by a pistol based on the M1911, as in real life the Model 39 was designed to replace the M1911 in US military service (although it failed to do so).
When viewing the weapon in the game's Service Record Special Projects menu, it displays Vasquez's famous "You always were an asshole, Gorman." quote.
