Semi-automatic firearm produced using 3D printer


Firearms produced using additive manufacturing techniques have been the subject of significant media attention and research. Most firearms printed from polymers have suffered from significant limitations to operational utility, primarily being single-shot weapons. The Shuty MP-1 is different. The latest in a series of videos detailing the development of the MP-1 9 x 19 mm pistol, produced using additive manufacturing (3D printing) techniques, shows a more refined version than earlier iterations being successfully test fired. A separate video details the disassembly of its components.

The developer claims that the weapon is ‘95%’ 3D printed, with the remained accounted for by various metal parts including the firing pin, springs, impact surface, and extra weight added to the bolt, hammer and barrel. The weapon is chambered for 9 x 19 mm – a fairly potent cartridge of choice for a 3D printed or improvised firearm – demonstrating the weapon’s seemingly acceptable level of safe construction. An example chambered in a less demanding cartridge such as .22 LR or even .32 ACP would prolong the smooth function and lifespan of its plastic components, especially as heat build up is reportedly an issue with long term use.

Although the prototype makes use of a standard 9 mm Glock barrel this isn’t by a major hurdle for those who may not have access to commercial firearm components. The eponymous improvised submachine gun design which inspired this weapon simply uses a length of seamless hydraulic steel tubing with an inner diameter of 9 mm as an expedient alternative, despite significant impacts to range and accuracy.

Although durability will undoubtedly present problems, when you consider the lack of ready access to firearms and significant price point of illicit weapons (e.g. an illegal submachine gun in the United Kingdom can sell for as much as £15,000), the concept of producing firearms of even limited utility may prove attractive to criminal elements. Furthermore, where as the appearance and function of a typical garage-made automatic weapon may put off potential customers from paying top prices, this particular weapon looks much like it was commercially produced and could potentially fool someone who lacks experience in handling firearms

Remember, all arms and munitions are dangerous. Treat all firearms as if they are loaded, and all munitions as if they are live, until you have personally confirmed otherwise. If you do not have specialist knowledge, never assume that arms or munitions are safe to handle until they have been inspected by a subject matter specialist. You should not approach, handle, move, operate, or modify arms and munitions unless explicitly trained to do so. If you encounter any unexploded ordnance (UXO) or explosive remnants of war (ERW), always remember the ‘ARMS’ acronym:

AVOID the area
RECORD all relevant information
MARK the area to warn others
SEEK assistance from the relevant authorities
