This paper model is a M-358 Talon, a heavy pistol in the game Mass Effect 3, the paper model was created by PepMaster. There are 83 parts on 10 pages. The M-358 Talon is a close-range pistol favored by Cerberus Guardians. Firing heavy-gauge shotgun pellets, it delivers massive trauma to unarmored targets. Its waste heat is sufficiently excessive that it carries six separate ammunition blocks, rotating like a twentieth-century revolver to prevent shaver jam or misfire due to premature melting of the shot.
The M-358 Talon is found during the mission Priority: The Citadel II inside a locked room. The door control is found in the nearby room used to circumvent a malfunctioning door. [Source: wikia]
