Zhou Baozhong went to the Northeast Army to buy guns, not to mention, the Wen Army, who was concerned about the front-line war, also came to find Jiang Tao. Pen, fun, pavilion www. biquge。 info

"Jiang Tao, have you had any ideas for developing a new gun type recently?" Wen Jun found Jiang Tao and asked.

"No, what's wrong, what's the situation on the front line recently?" When Jiang Tao heard this, he knew that the Wen army must have known what was going on on the front line before he came to find him, otherwise he would not have been busy with the recent training of armored troops.

"That's right, you also know that this group of little Japan will charge at every turn when fighting with us, although you have equipped the front line with mirror boxes, but only grassroots officers can be equipped, and ordinary soldiers still have to rely on bayonets if they are close to the little devils. Although I don't want to admit it, this little devil's kung fu with bayonets is really good, and our soldiers may not be able to fight with bayonets. Wen Jun directly told Jiang Tao the problem.

"That's right. Brother Jun, give me some time to think about it. As soon as he heard Wen Jun's request, the idea of making an assault rifle popped up in Jiang Tao's mind. The famous world's first gun, the AK47, became his first target. But soon Jiang Tao found the problem, ammunition, if you want to use an assault rifle, the ammunition must be redesigned, the current rifle bullet is not suitable for an automatic rifle, the current rifle bullet kinetic energy is too large, if the automatic rifle uses the current rifle cartridge, the powerful recoil will make the assault rifle bullet float to the sky, not to mention that the AK-47 has never been a firearm known for its accuracy.

In addition, the use of intermediate power bullets means a great increase in logistical pressure, automatic rifles consume ammunition much faster than bolt-action rifles, you must know that Jiang Tao's bullet production is not large, and now it is impossible to immediately switch to automatic rifles, so the original rifle bullet production line has to be maintained, so if you switch to automatic rifles, Jiang Tao They will have to maintain pistol bullets, rifle bullets, automatic rifle bullets and machine gun bullets at the same time 4 production lines, which is not good news for logistics.

Therefore, Jiang Tao immediately dispelled the idea of producing automatic rifles, and the remaining two methods were to produce semi-automatic rifles and submachine guns.

The representative of the semi-automatic rifle is Eagle Sauce's M1-Garand, Maozi's SVT-40 (the reason why the 56 and a half used in China later is not considered here is the same as the above, the 56 and a half are not used full-power bullets, but the 7.62*39 intermediate power bullets used) and Mauser's successor G43 semi-automatic rifle. However, all three semi-automatic rifles have their own problems. The German G43 semi-automatic rifle design is precise and unique, but his requirements for processing technology are also the highest, Maozi's SVT-40 does not inherit the characteristics of Maozi's products that have always been simple and rude, but is more similar to the German's design is too complex, difficult to maintain, and has a high failure rate. Only a handful of elite units (the Red Navy of the Soviet Union) would find this gun useful. The M1-Garland of the United States could not escape this strange circle, although the processing technology is simpler than the previous two, high reliability, high shooting accuracy, easy to disassemble and clean, but his weight is much heavier than the previous two, which is not conducive to Asians to carry and use. And the double-row leakage bullet it adopts has certain deficiencies in the continuous supply of ammunition, although the gun can be divided into single round loading, full magazine and half-magazine loading, when the magazine pressed into the magazine at one time in actual combat is very difficult to reload the magazine again before the bullet is exhausted, and because the magazine bullet is exposed, sometimes the bullet is not necessarily aligned with the double garden opening, in order to make the bullet align the opening soldier often knocks a few times on the steel helmet to make it aligned.

However, the development of semi-automatic rifles is imperative, Jiang Tao plans to carry out preliminary development first, and equip troops on a small scale, and the armored regiment of the civilian army is very suitable. Jiang Tao planned to use the M1-Garand of the United States as the prototype, remove the magazine and change it to a magazine commonly used in later generations to feed ammunition, and at the same time shorten the length of the gun, thereby reducing the weight of the gun and making it more suitable for Asian use. But even though the structure of the M1-Garand is simple in a semi-automatic rifle, for Jiang Tao, what he needs is to be able to quickly produce a large number of equipped guns, and he can produce them slowly, but the soldiers on the front line can't wait.

So Jiang Tao's decision is a submachine gun, initially Jiang Tao considered a simple structure, rapid production, low price known for the plumber firearm - Stern submachine gun, this gun is very strong, and the recoil is low, simple maintenance, even as long as a simple wipe, it is designed to not even need gun oil when maintaining, the most important thing is that it uses pistol cartridges, but this gun has a fatal problem, his safety performance is too poor.

Its magazine and ammunition feeding device copied the German MP38, and it often jammed; Secondly, its safety device was very unreliable, and it would misfire at the slightest touch, and many Allied soldiers were wounded or even killed by their own submachine guns before they reached the front line. Some armies have a rule that Nardon submachine guns should be in front to avoid accidentally injuring their comrades. The British soldiers believed that if they threw the Stern submachine gun, they would definitely injure the enemy with a misfiring bullet.

In line with the attitude of being responsible for the soldiers of the Northeast Army, Jiang Tao decided to adopt a powerful upgrade of the Stern submachine gun, the American M3A1 submachine gun. For the original M3, the M3-style crank, the first loading handle is worn out, and it is inconvenient to use, so the crank is removed and the bolt is directly pulled by hand. The "L" shaped lever in the handle and the handle box was eliminated, and the size of the shell window was increased to the rear, and instead of the handle was a large hole in the bolt that could be inserted into the finger, and the bolt could be pulled to the rear as long as the finger was inserted into the hole. The oversized shell-throwing window is also equipped with a dust cover, which has a protrusion on the inside of the dust cover, and the dust cover is covered so that the protrusion enters another large hole at the rear of the bolt, plays the role of fixing the bolt, and the protrusion can also enter the large hole in the front of the bolt when the bolt is in the rear position and plays an insurance role. The jamming of the magazine sticking outward on the left side of the M3 gun became the cause of the magazine falling off accident due to carelessness. The M3A1 submachine gun has an additional retainer around the magazine jam to prevent the magazine from falling off. In addition, in accordance with the requirements of the actual combat troops, a place was added to the grip for placing the cartridge used in the maintenance of the submachine gun. Although the rate of fire decreased compared to the Stern-type submachine gun, the accuracy of the shot increased considerably. It is more in line with the needs of actual combat.

Considering logistical considerations, Jiang Tao replaced the barrel with an 11.43 caliber so that he could use the 11.43mm pistol cartridge that was common to his troops.

The structure of this submachine gun is also simple, even much simpler than the structure of the pistol used by the Northeast Army, after the drawings of Jiang Tao's exchange office were handed over to Luneng, Luneng just simply welded the stamped parts together, and a submachine gun was produced. After loading the pistol bullet, it can also shoot easily, the only problem is that because of the use of a larger caliber than the original caliber, the recoil has become larger, and the accuracy has decreased a lot when firing in bursts, Jiang Tao had to adjust the rate of fire again, but the reason for the use of large-caliber bullets, its stationary effect has also been strengthened, and it is easier to use for the Japanese charge, as long as it is taken by one shot, it must be knocked down with one shot, and there is no way to fight again. This can be regarded as a loss, but there must be gain.
