Select fire machine pistol: a lengthened slide and barrel over a squared receiver, a long magazine through the grip, a folding forward brace under the muzzle and a stubby arm brace behind the frame. Dimensions 0.08 by 0.25 by 0.32 m (X by Y by Z). Metre units, +Y up, +Z front; the origin sits on the ground at the footprint centre unless stated otherwise. Wind blown snow, packed track snow, blue glacier ice, dark teal and safety orange station cladding, off white insulated panel, galvanised steel, gunmetal, black polymer, white and grey and teal cold weather cloth, warm window glow and cold blue marker light. Rigid node-transform clips magazine-open, magazine-close, slide-open, slide-close drive the named parts on their own pivots. There is no skinning and no skeleton; every other surface is static. Original invented archetype: it copies no real firearm and carries no maker, model or product name, and no markings, logos or lettering. The bore is a modelled recess and fires nothing; there is no muzzle flash, projectile, recoil, ammunition count or damage data. It stands on its magazine floor plate and grip toe at y = 0. The magazine and the slide are the only moving parts.
