This is my version of the prop from the movie. This is not a real gun, just a toy. the barrel is plugged as is the cylinder. This is built in AutoCAD 2013. Again Just a PROP.

Version 2 is done. no barrel or cylinder plugs. plus the trigger works the hammer. just cock the hammer and pull the trigger.

Here is the fully printed version: https://www.etsy.com/listing/517398697/hellboy-good-samaritan-pistol-3d-printed?ref=shop_home_feat_2

designed in Auto cad 2013, lots of parts, no screws needed only some glue for the handle. the pins should hold the other parts. use 3mm plastic for the small pins.
