Authoring semi-automatic guns that do not require legal & possessing registration with 3D printers, fierce successes who also succeeded in firing test appeared

Attempts to create handguns with 3D printers are taking place all over the world,An arrested person comes out even in JapanThe situation that anyone can print out a gun is considered to be a big problem, and the necessity of regulation is debated. Meanwhile, a person who made a semi-automatic gun with a 3D printer without touching gun control has appeared, and its performance is released in a movie.

The state of the shooting experiment of a self-made semi-automatic gun can be confirmed in the following movie.

This semi-automatic gun "Shuty MP-1"Was made by a 47-year-old man named as" Derwood "(pseudonym) living in West Virginia, USA. It was a semi-automatic gun named "Shuty MP-1" that released the state of launch, 95% of the parts were 3D printed with PLA resin.

In addition, Mr. Derwood has released a movie showing how to assemble Shuty MP - 1.

This is a semi-automatic gun "Shuty MP-1" created by Mr. Derwood with a 3D printer


Mr. Derwood, laying the parts that make up Shuty MP - 1 on the desk a lot and assembling the parts of the gun.




We are screw-fastening at required points. Shuty MP-1 said that the necessary parts of strength and springs etc. are improving durability by using metal parts of ready-made products. Therefore, "It is 95% of the gun that 3D print was done".


Assembling work of the magazine (magazine) part.


I will put ammo.



I will only set them up afterwards.


In barrel (barrel) is like this.


Tubular parts containing metal ......


Insert inside.


Insert the metal rod and thread the spring.


Close the lid and complete.


Attach the screw to slide ... ....


Gun barrel attached to gun main body.


It is a part to which quite a large impact is applied at the time of launch, so it is fixed firmly with screws.


Check the slide level at this stage.


Finally this part ......


Once installed on the top of the gun the gun body is complete.


If you install a magazine with ammunition ... ...


Completion of Shuty MP-1.


According to Mr. Derwood, all metal parts used to create Shuty MP - 1 are general purpose goods, not subject to gun control, Shuty MP - 1 is a legally produced gun and obligation to register There is nothing. Shuty MP-1 has the ability to shoot bullets continuously as it is in a movie, allowing up to 18 shots. Since there is a possibility that resin parts will be deformed and broken if 18 or more injections are done, it is necessary to cool after 18 shots. However, it seems that it is possible to fire the bullet again if only an interval is set.

Mr. Derwood finds pleasure in making a gun "with his own hands", so his creation with a 3D printer is completely personal. I do not feel like transferring my own guns to others and I do not feel like publishing design drawings.
