As you can see, the process starts off by using forging machines to shape the gun's major components and then machining them to the final size. Then, a milling machine is used to carve out the cylinder and a technician hand files some of the parts to fit properly. Then he does a little bit of assembly and stamps the model # and serial # to the frame. Another artist adds engraving. Then they do some metal treatment to the parts, a process called case hardening that we studied a while ago. Then, assembly of all the parts proceeds, as the barrel, cylinder, frame and trigger assembly are all put together into a working revolver. Finally, the revolver is sent to a Government facility to perform proof testing.
