Kingsman Underbarrel Shotgun

Kingsman underbarrel shotgun for TT-33 pistol. Functional trigger included. Requires 2mm rods/pins (I use BBQ skewers) for moving parts and ~3x10mm (DxL) spring to function (optional). Designed to work with https://www.dropbox.com/s/t0jdvz23rb9a0z7/TT-33.stl?dl=0 but requires modification of this model if the trigger is to be integrated. Note: this might not fit an actual shotgun shell and has not been fully tested at this stage.
