This is actually due to such a gun, although it seems that the cost is relatively low. Then in the process of use, the firepower is also very fierce, but it has a very obvious shortcoming, that is, such a gun, its range is very long. So because of its long range, if you want to use this gun, you must get close to the enemy.

But in fact, this kind of gun is actually opposite to the tactics adopted by China in War of Resistance against Japanese Aggression. As we all know, most of the tactics adopted by our country during the period of War of Resistance against Japanese Aggression were guerrilla warfare, so guerrilla warfare, in fact, his requirement for guns is to hope that the range can be longer.

Because guerrilla warfare is mostly in the enemy's imperceptible position, such a position is actually far from the enemy. If such a rifle is used at a distance from the enemy, there is no way to achieve the final design goal.

Therefore, not many people bought submachine guns at that time. In fact, although submachine guns have strong firepower, they can only be used in close combat. At that time, during the War of Resistance against Japanese Aggression period, in fact, most of our troops used pistols or other rifles. There is a key reason, that is, because of this submachine gun, he has no advantage in the field. Coupled with this, it is actually difficult to achieve a goal of the final design.
