Anti-Japanese War, weapons designer at Fengtian Arsenal
Chapter 247 PPS43 Submachine Gun
This urban street fighting exposed many problems, and Li Qinwu had to carry out a major replacement of his equipment to address these problems. With his current industrial strength, plus the blessing of the incredible material ceramic steel, he can already afford to update the weapons of tens of thousands of people.
Li Qinwu sat at the drawing table, put down the drawing paper, and sharpened his pencil. He lit a cigarette for himself, took a deep breath, and picked up a Sweeper submachine gun beside the drawing table and looked at it carefully.
This gun was a weapon used by a disciplinary army soldier. He said he fought throughout the Battle of Shanghai and fired more than 2000 rounds of ammunition with this gun.
This gun was the first batch of ceramic steel guns to be put into actual combat. Except for the gun body, everything including the barrel is made of ceramic steel. Li Qinwu was curious about the wear and tear of the gun.
He disassembled the gun into parts in a few seconds, picked up the barrel and looked at it carefully. He felt the rifling in the ceramic steel barrel with his little finger, then shone the flashlight into the barrel. Well, it was slightly worn, but the main body was intact and fully functional.
Putting down the gun barrel, Li Qinwu smiled. The wear resistance of the ceramic steel barrel was higher than he imagined.
If traditional materials were used to make the barrel, a submachine gun barrel could fire about 7000 to 1 rounds, while the breech of a ceramic steel barrel would remain intact after firing 2000 rounds. It would apparently continue to fire about 4000 to 5000 rounds before becoming scrapped, proving that ceramic steel barrels are reliable.
Li Qinwu was deeply moved. This material with low cost, high plasticity, high hardness and lighter weight than traditional steel was actually judged as unqualified by the Human Empire in Warhammer 40k. How incredible is the combat intensity of Warhammer 40k?
Retracting his thoughts, Li Qinwu focused his attention on the receiver of the submachine gun. In this battle, the biggest problem exposed by this gun was its low reliability, and the exposed receiver was the culprit!
Such a big hole exposes the internal structure of the gun, and a large recoil spring can be seen clearly. Any debris on the dusty battlefield can get in!
Li Qinwu picked up the receiver and moved it on the table. Immediately, some fine sand and stones appeared on the table. He shook his head, threw the receiver away, and lay on the chair with his hands on his head, staring at the ceiling. He was wondering, is there any need to improve this thing?
The foundation of the Sten submachine gun is there, and the structure of the gun has been simplified to the extreme. Li Qinwu can't think of any way to cover the exposed receiver. It's not that there is no way, but is it necessary to study a complicated receiver on such a simple gun body?
"Instead of continuing research on this gun with a low ceiling, it's better to start from scratch."
Li Qinwu murmured.
But the question is, what gun should we copy? Which gun is widely used, low-cost and highly reliable?
As he was thinking, Li Qinwu glanced at a pile of various weapons piled against the wall, among which was a flamethrower submachine gun, also known as the PPSh.
His eyes stayed on the gun for a long time, and suddenly he slapped his forehead.
"Fuck! How could I forget about PPSha's third sister, the most powerful submachine gun in World War II!"
Li Qinwu sat up straight, picked up the pen and started drawing quickly on the paper. He worked on this drawing for 5 days without sleep or food. After 5 days, there were more than 40 drawings on the drawing table. The top drawing was a three-view drawing. The gun was a pps43 submachine gun.
Some people may not know the PPS43, so let’s change its name to my country’s Type submachine gun, the Lei Feng rifle. Now you should be familiar with it.
The production background of PPS43 was that Germany invaded the Soviet Union on a large scale, which led to the loss of many industrialized cities in the Soviet Union. At this time, the cost of mass-equipping the Soviet army with the PPSh, also known as the PPS41, was still too high. The Soviet army needed a submachine gun that was cheaper than the PPSh and had properties comparable to the PPSh, so the Soviet Union developed the PPS42.
The pps42 is made of stamped parts, welded and riveted all over. The gun body is very compact and neat. It adopts a folding buttstock and an extended magazine well, so that the shooter can hold and shoot, which is equivalent to having a built-in front grip. Most importantly, it is very reliable!
There is no exposed structure on the PPS42 gun body and the sealing is quite good. In comparison, the Sten submachine gun is like a bitch with its legs spread out!
More importantly, this gun has a low-cost attribute that is not inferior to the Sten submachine gun. Any small factory with a 50-ton stamping press can produce it, and Li Qinwu has ceramic steel, so the production difficulty is further reduced.
Of course, what Li Qinwu wanted to copy was not PPS42, but PPS43. There is not much difference between PPS43 and PPS42. It is just that PPS43 shortens the gun body based on PPS42, making the structure more compact and saving more materials!
The length of the pps43 stock is 820mm when it is opened, and 610mm when it is folded. The empty gun weighs 3.36kg and has only a continuous firing function.
The fact that this gun was able to gain the reputation of being the most powerful submachine gun in World War II proved that its structure was quite mature and Li Qinwu could not find any room for improvement.
He threw the drawings directly onto the production line, produced 100 units first, and opened portals to take them to Southeast Asia, Chongqing, Henan, and Hutoushan for multi-terrain and multi-climate testing.
In the future, the Punishment Army’s submachine guns will be equipped with this thing. Of course, the main automatic weapon sold abroad will also be this thing. Li Qinwu gave it the number Spitfire-2.
Anyway, in the original time and space, PPS43 was the third sister of Poposha, and she looks similar to Poposha, so it's not bad to be named Spitfire-2.
After the Spitfire-2 passes the test, Li Qinwu will stop the production line of the Sweeper. The Sweeper's foundation is too poor, and Li Qinwu does not plan to continue production.
After arranging the test of the Spitfire-2, Li Qinwu took a nap to regain some energy, checked the development of various industries, and returned to the drawing table to work again.
The Punishment Army is stronger than other military branches in terms of physical fitness and armor equipment. The old bolt-action rifles and submachine guns seriously curb the combat effectiveness of the Punishment Army. Li Qinwu must prepare more advanced weapons for them!
He now has three R&D goals.
First, semi-automatic rifles that fire full-power bullets, second, automatic rifles that fire intermediate-power rifle bullets, third, belt-fed light machine guns, and vehicle-mounted machine guns that are modified by adding heavy barrels.
