In the Line of Fire Assassin Gun - 1993
Watch Here: http://youtu.be/oH2UqXZ6yOk
Resin prop replica of the composite gun made by John Malkovich (Mitch Leary) in the movie, In the Line of Fire. Leary creates this plastic gun to slip past security into a re-election campaign dinner for the President of the United States. Malkovich faces off against the Secret Service agent assigned to protect the president, Frank Horrigan (Clint Eastwood). When at the hotel where the President is staying, Leary assembles the weapon under the party table, and had previously hidden the ammunition in a rabbit's foot keychain, and the springs in a pen. The gun is a double barrel, single action weapon, and has working trigger action (does not fire rounds). Each barrel is manually cocked by the levers at the top of the weapon, and the gun also disassembles into several sections.
How the trigger action works:
Just like in the movie, the firing pin is pulled back by the dowel, then the dowel is pressed down to lock the firing pin. When the trigger is pulled, it pushes up on the dowel until the dowel becomes free, allowing the spring to push the pin forward.
Movie was released in 1993

While 3D printing technology has been around since the 1980s, it was not until the early 2010s that the printers became widely available commercially.[3] The first working 3D printer was created in 1984 by Chuck Hull of 3D Systems Corp.[4] Since the start of the 21st century there has been a large growth in the sales of these machines, and their price has dropped substantially.[5] According to Wohlers Associates, a consultancy, the market for 3D printers and services was worth $2.2 billion worldwide in 2012, up 29% from 2011.[6]
The 3D printing technology is used for both prototyping and distributed manufacturing with applications in architecture, construction (AEC), industrial design, automotive, aerospace, military, engineering, civil engineering, dental and medical industries, biotech (human tissue replacement), fashion, footwear, jewelry, eyewear, education, geographic information systems, food, and many other fields. One study has found[7] that open source 3D printing could become a mass market item because domestic 3D printers can offset their capital costs by enabling consumers to avoid costs associated with purchasing common household objects.[8]
