is specially developed for secret agents.
Agents, special operations, and commercial protection have slowly formed a mature system since the beginning of the First World War and the Second World War. In various special operations and special operations In this issue, a concealed weapon that can be used as a hand is particularly important. This issue of the weapon lecture hall analyzes a foldable submachine gun that is only in the prototype stage-the Magpu FMG-9 submachine gun developed by the US Magpu Industries.
Creative FMG-9 folding submachine gun
The FMG in Magpu FMG-9 is the abbreviation of FoldingMachine Gun, that is, folding submachine gun. 9 refers to the firing of 9MM caliber bullets. The concept of a folding submachine gun actually existed very early. Before the outbreak of World War II, France began to develop a submachine gun that could be carried in a concealed manner, and designed the MGD PM9 collapsible submachine gun. The buttstock of this gun was folded. Both the magazine and the magazine can be folded forward, which is considered to be an earlier case of folding submachine guns.
After World War II, the world situation has become very turbulent, and various terrorist and Cold War agents have emerged one after another. Therefore, all countries also hope to have a team that can be carried by individuals in concealment and can provide close range if necessary. Submachine gun with stronger firepower.
At that time, the American Lacey Company developed the world's first practical folding submachine gun-FMG submachine gun. Almost at the same time, a personal weapon manufacturer in the United States also produced a A more unique folding weapon called the UC-M21 submachine gun. These two submachine guns have not been well developed in the United States, but they have gained attention from their old opponents. In the 1990s, Russia's FMG submachine gun Based on the development of the PP-90 folding submachine gun, it was officially mass-produced for use by agents and security personnel. This is the only folding submachine gun officially used in mass production.
Then with the end of the Cold War and the initial stabilization of the world situation, the demand for such concealed weapons is not so great, so there has been no major action until the 2008 US SHOW SHOW 2008 It was only at the exhibition that people's vision was re-entered, and what is on display at this exhibition is today's protagonist-FMG-9 folding submachine gun sample gun.
The appearance design of the FMG-9 folding submachine gun that was exhibited at that time almost merged the various elements of the front folding submachine gun. The appearance looks very small and concealed, similar to the appearance of the UC-M21 submachine gun. It's very similar. The overall appearance is made of a lot of modern engineering plastics. When folded, it looks like an ordinary plastic tool box, so it can be disguised as a small package or a laptop battery.
The upper part of the tool box is a detachable handle. After unfolding, this handle can be used as a mechanical aiming mechanism. In front of the tool box is a detachable strong light. In the folded state, the length is only 262 mm, and the weight of the gun is 0.5 kg.
This light weight is due to the use of a lightweight polymer material, and it can even be carried in a pocket after removing the handle, so the FMG-9 is folded The submachine gun is very convenient for daily concealed carrying.
And when you need to use it, it is very convenient and fast to unfold. To unfold the FMG-9 folding submachine gun, you only need to carry the handle and pull the trash handle back to directly use the receiver parts. The inertia and the action of the spring can automatically unfold the butt and the grip one by one and lock them in place, and then directly load the gun to shoot.
Its receiver adopts a two-stage receiver design. The two receivers are connected by a rotating shaft and quickly folded or unfolded around the rotating shaft. The rear structure is equivalent to The structure of the buttstock has a protrusion at the tail that can completely cover the muzzle part after being folded, and there is also a cover at the link of the two parts.After folding, the gap at the rear of the receiver is automatically covered, so that the entire mechanism is folded to form a relatively complete box shape.
with a detachable handle on the upper part for carrying, of course, this handle is installed on the Picatinny rail added on the top of the receiver, which can be removed and replaced with other sights A device such as a red dot or a magnifier for aiming.
In addition to these two structures, there is also a magazine socket and trigger structure near the hinged position. The magazine socket is shaped like the grip of a Glock pistol. It can be used as a grip at the time, and insert the magazine at the bottom for bombing. The back of the grip has a locking hook, so when it is fully extended in place, this hook will be in contact with the slot on the grip seat at the rear of the receiver. Fasten to lock the grip for stable shooting.
The trigger is designed on the front of the grip. The external trigger guard is hinged. When the rear stock is folded, the trigger guard will fold forward together with the trigger, so that it can be used as a stock When it is rotated 180° downward to overlap with the bottom of the gun body, the grip, magazine and trigger mechanism can be hidden inside to form a complete box structure.
In terms of the structure of the bolt mechanism, the bolt mechanism of the whole gun is basically designed according to the principle of the Glock 17 series pistols. It can also be considered that the weapon part of the FMG9 is equivalent to an elongated barrel Glock automatic pistol, its automatic machine and firing mechanism are the structure of Glock pistol, except that the grip and trigger guard are rotatable, they are almost the same. The gun machine adopts the principle of recoil action, and the firing mechanism adopts The firing mechanism of the Glock pistol uses the Glock 17 magazine for the magazine, and even the design of the magazine is exactly the same.
Because the launching mechanism is hidden inside, in order to facilitate troubleshooting of the internal bolt action, the upper part of the front receiver of the FMG9 can actually be rotated and opened, and unlocked by a button on the rear of the handle turn on.
When opened, you can see that the internal structure is equivalent to a pistol with a long barrel. The loading method is to use the pull handle to pull the load, and the pull handle is a small upper side of the receiver. structure.
Because the prototype adopts the Glock 17 series pistol mechanism, it can be semi-automatic shooting. Of course, if the subsequent mass production is replaced with the Glock 18 series pistol, the gun mechanism can realize automatic shooting. of.
There is a piece of metal under the front receiver. This piece of metal is foldable and can be used as a finger baffle for the shooter during launch, or a small front grip for the shooter Take the auxiliary gun and shoot.
The shell ejection window is designed on the right side of the front receiver, and the ammunition supply method is 20 rounds or 32 rounds of the Glock 17 pistol. Of course, the 18 series of large capacity can also be used Magazines, of which 20-round magazines can be inserted into the grip and folded together with the gun, while larger-capacity magazines can only be inserted after unfolding. The ammunition uses a standard 9×19mm Parabellum pistol. The bullet, rate of fire or power is basically the same as a pistol.
Take the structure of the Glock 18 pistol as an example. The theoretical rate of fire can reach 1200 rpm, the muzzle velocity is 380 m / s, and the effective range is 50 meters. Of course, because it uses extra With the addition of the buttstock and grip, the effective range will be a little higher than that of a pistol alone, basically reaching 120 meters.
Compared with the pistol, the FMG-9 folding submachine gun benefits from the unique concealed structure design. When carried, it will be more concealed than the pistol. When unfolded, the FMG-9 The length of the foldable submachine gun is 503 mm. Although the unfolding method is very convenient, it can be fully unfolded and fired only by pressing it. Basically, it can be opened and ready for battle within 2 to 3 seconds. But it’s a little troublesome when put away, After all, there are many buckle structures. When stowing, you need to first press down the front small grip, then press down on the grip and overwhelm the grip, then release the butt but rotate the butt in place. Complete the folding process.
FMG-9 FMG-9 folding submachine gun can be installed in the holster, carrying bag, handbag, or even in the trouser pocket when folded. Even if it is inspected, no one will think it is a weapon, so this gun is very concealed. It can be said that it is specially made for special occupations that are secretly affiliated with national organizations such as spies. It can be more concealed when performing tasks. Approach the goal.
However, because of its structural limitations, it cannot perform traditional combat missions like traditional submachine guns, so it can only exist as a special weapon, plus its core components are directly used off-the-shelf Glock Automatic pistol, so the cost of research and development is relatively low, because this gun has only developed to the prototype stage and has not been mass-produced, so its price is unknown.
But in 2010, Magpul once cooperated with other organizations to launch the airsoft gun kit FPG for this gun for civilian toy sales. At that time, this kit was priced at about US$350, excluding the Glock 18C pistol mechanism. The price of the service version should be similar. Although it was not officially mass-produced in the end, the design concept of this weapon is still very worthy of our study and reference. What do you think?
