Siheyuan starts from a better life

Chapter 459, Design Concept

Of course, the drawings of the Type 64 pistol cannot be found online, but there are many drawings of other pistols. After Jiang Yan’s careful selection and considering the current production level of the country, Jiang Yan fell in love with the Glock 26 Based on the compact pistol, a new Type 64 pistol was developed.

Generally speaking the biggest dilemma with self-defense pistols is the balance between the size of the gun and its capabilities.Because of the pursuit of a high degree of concealment, the size of the self-defense pistol is designed to be as compact as possible.But the compact structure brings a series of problems.The first is aiming. The crosshairs of most self-defense pistols are too small to aim in an emergency (self-defense in emergencies requires quick release of the gun. In this case, rough aiming is generally implemented, but even if Aiming slightly requires the help of a crosshair), and even the crosshairs of some self-defense pistols are not visible at all.

The second is the poor ergonomics, which makes many self-defense pistols difficult to operate under combat conditions; the third is the ammunition problem. Although the bullets fired by the self-defense pistol are lethal enough, they lack the most important stopping power of the pistol (relatively speaking, The stopping power of large caliber handgun ammunition is much stronger than that of small caliber rounds. Seriously, the stopping power of a self-defense pistol is impressive when using qualified ammunition. Such a gun is simply better than nothing because of its stopping power. Too low, causing law enforcement officers to be very cautious about the use of self-defense pistols; finally, due to the compact size of self-defense pistols, their ammunition capacity is naturally small. Generally, self-defense pistols only have 6-7 bullets. Coupled with the use of low-power ammunition, this will Users are placed at a serious disadvantage.

The reason why I fell in love with this pistol is because the most obvious thing about this pistol is the unique buffer spring system developed for it.This is a double re-feeding spring device, with two springs nested together.While this is not new technology, the use of this method (where two springs provide power throughout the entire recoil cycle) is innovative in the field of firearms manufacturing.

Jiang Yan calculated that such a double-row magazine design could allow the pistol to hold a maximum of 11 rounds of bullets. The original Type 64 pistol used a single magazine for ammunition, and the maximum capacity was only seven rounds. In order to avoid springs, generally only With a capacity of about five rounds and using a double-row magazine design, the capacity of this new Type 64 pistol can be almost doubled and can be continuously output. Not only that, Jiang Yan also designed a standard magazine and specially audited it to be able to hold 20 rounds. A large-capacity magazine that fires bullets, but the magazine is slightly protruding.

This pistol consists of six major parts: barrel, slide, recoil spring, slide base, firing mechanism and magazine.The automatic mode of the pistol Jiang Yan intends to adopt is the free bolt type, which is equipped with mechanisms such as linked firing, empty chamber hang-up, magazine latch, and chamber loaded indicator; the safety mechanism includes safety insurance, in-position safety, automatic safety, and shooting safety, etc. function.

However, although it has many functions, considering the need for a large number of troops to be quickly equipped, Jiang Yan plans to use stamping mode to manufacture the pistol. Since he provides a large amount of alloys, this gun also plans to use new alloys to reduce weight.

Jiang Yan almost recorded his general intention of designing this pistol. The appearance of the pistol was also designed. Since it was based on the Glock 26 compact pistol, the sketch design was similar to the historical Type 64 pistol. There are some differences. Not to mention other things, this gun is larger than the Type 64 pistol in history, and smaller than the Type 54 pistol. However, as long as you don’t wear tight pants, you can easily put it in your pocket. For this reason, Jiang Yan also thoughtfully designed a holster for the pistol.

"Boss, it's time to eat." Just when Jiang Yan was about to design the detailed parts of the pistol, He Yuzhu's voice called him to eat came from outside the study, and Jiang Yan came directly from the space to his study.He looked up at the watch on his wrist and unknowingly an hour had passed. The flow rate between the space and the outside was one to ten. He had been in space for ten hours. No wonder he was so hungry.

"Zhuzi, what are you going to eat tonight?" Jiang Yan asked He Yuzhu after leaving the study.

"Grandma wants to drink pimple soup, so I made some three-fresh pimple soup and fried some vegetables."

Three delicacies pimple soup is something Jiang Yan loves to drink. After hearing what He Yuzhu said, he strode towards the restaurant. When Jiang Yan approached, he saw that grandma and the others had already eaten, so Jiang Yan took the opportunity to sit next to grandma. He sat down, then took the bowl of pimple soup handed over by Qin Huairu, and took a bite. I have to say that Zhu Zhu's craftsmanship is quite good, and the pimple soup is delicious.

"Boy Yan, Ruirui has been gone for two months! You didn't ask her when she would come back. Grandma already misses him." At this time, the old lady who put down the bowl asked.

"I just asked two days ago. She said that she originally planned to go there for four months and that she would come back after completing the mission. You don't have to worry. Didn't she send you a letter two days ago?" Jiang Yan was eating vegetables. While answering grandma's questions.Jiang Yan had no idea when Jiang Sirui would come back. By saying this, he was trying to deceive his grandmother. As a scientific researcher, Jiang Yan knew that if the project was not completed, she might not be able to come back. He said this just to comfort her. My own grandma.

"Hey! You all have eaten." The appearance of Liuzi interrupted Grandma Fu's next words, but Liuzi was also followed by Yan Bugui.

"The third uncle is here. Have you eaten? If not, let's eat together." Seeing the third uncle coming, Jiang Yan was embarrassed not to entertain him, so he asked.

"Not yet! Didn't I hear that Jiang Yan's research institute was in the newspaper? Third uncle, I'm here to congratulate you."

When Yan Bugui, the third uncle, was talking, he was looking straight at Jiang Yan and their dining table, his Adam's apple twitching.

Jiang Yan was quite clear about Yan Bugui's purpose of coming here. It was true that Yan Laoxi came to congratulate him and take advantage of him. However, it was just a meal, so Jiang Yan didn't take it to heart yet.

So Jiang Yan looked at him and smiled and said: "Thank you, Third Uncle. We have just eaten. If Third Uncle doesn't mind, sit down and eat a little. Let's fill our stomachs first and then drink some." "

"Then I'm not welcome. To tell you the truth, the third uncle's family hasn't eaten refined grains for a while." He said, picking up the white flour steamed bun and taking a big bite.

Hearing what the third uncle said, He Yuzhu, who was eating next to him, said: "No, third uncle, there are three people in your family making money now! You can make a lot of money this month. You should be able to live a comfortable life. Today there are Yan Jiefang had a share of the things, so he didn’t take them back.”

"It's not that there is a ration, isn't it? Everyone's ration is just like that. Even if you have money, you can't buy anything! Besides, in our family, only one person, Jiefang, works in the research institute, and he only brings back one piece of stuff. He can't compare with you. , there are four people in your family working in the research institute, and they bring back four benefits."

You see, the third uncle Yan Bugui made this calculation very shrewdly. As soon as he said these words, everyone at the dinner table fell silent.
