The long slide pistol with a pistol suppressor on its threaded muzzle, a reflex sight in the slide cut and a light on the rail. Dimensions 0.042 x 0.189 x 0.434 m (X x Y x Z). Origin at the footprint centre, resting on y = 0; metre units, +Y up, muzzle and point toward +Z. Named pivots: slide at (0, 0.1197, -0.0711); hammer at (0, 0.0855, -0.1631); magazine at (0, 0.0865, -0.1287). Connectors: muzzle muzzle at (0, 0.1209, 0.0629) facing +Z; magazine magazine at (0, 0.0865, -0.1287) facing -Y; optic optic-rail at (0, 0.1453, -0.1591) facing +Y; underbarrel underbarrel at (0, 0.0783, 0.0029) facing -Y. Fitted loadout: the attachments are modelled in place on the host sockets, which stay declared so a developer can strip and refit it. The slide, the hammer and the magazine each work on their own pivot. The trigger linkage, the disconnector, the extractor and the recoil spring are modelled as solids but are deliberately static: a rigid node transform cannot drive a linkage, and faking one costs a consumer more than it gives. Rigid node-transform clips slide-open, slide-close, magazine-open, magazine-close, cock drive named nodes on their own pivots. No skinning and no skeleton. Blued gunmetal, bright machined steel, dark anodised alloy, black and dark earth polymer, rubber, walnut, brass, copper, leather, olive paint, optical glass, concrete and emissive red, green and warm white for reticles, lasers, tritium and lamps. Physically based flat colours with no texture maps. Original invented design: no real make, model, manufacturer or marking is represented.
