The QSB-11 (Chinese: 11式匕首枪; pinyin: 11 shì bǐshǒu qiāng) or Type 11 dagger pistol, is a knife pistol is designed by Chinese defense manufacturer 974 factory. for paratroopers, special forces, and special police forces of the People's Liberation Army and People's Armed Police. The pistol's designation "QSZ" stands for "'light weapon' (qīng wŭqì)— 'dagger gun' (bǐshǒuqiāng)—'manual' (shǒudòng)".
History
[edit]Research for the QSB-11 began in the 2000s as the PLA changed ammo use from 7.62mm to 5.8mm.
Design
[edit]Knife guns are a combination of the dagger and the modern firearm by integrating the firing mechanism into the dagger. QSB-11 consists of the blade, gun, sight, firing mechanism, and sheath.[1] It is lightweight, simple in structure, versatile, and easy to use. In addition to the functions of a pistol and dagger, it also has many other functions such as sawing, filing, cutting (only in combination with the sheath), and stabbing. It can also be used for opening cans and bottle caps. It can remove obstacles in harsh environments, which increases its practicality in battlefield scenarios.[2]
The QSB-11 shows features of a survival knife. From the QSB-91, the blade was lengthened to 166mm, and the blade shape was improved. The sheath is multi-purpose; it can be used for cutting when used in combination with the knife and features a sharpening stone. The saw file on the spine of the blade can be used for filing.
The firing pin and mechanism are located within a screw-in cover of the hilt. The trigger is activated by pushing it forward rather than pulling; the thumb is used to do this. The safety is located in front of the trigger and prevents the user from pushing the trigger.
Unlike the QSB-91, which has a common firing mechanism for all four barrels, the QSB-11 is equipped with an individual firing mechanism for each barrel. After pulling the trigger, the hammer, under the action of spring force, aligns with the firing pin hole, strikes the primer of the bullet to ignite the firing charge, generating gas to push the bullet along the rifling to fire out of the barrel. If there is a dud, it is possible to pull the trigger again and directly fire the next round. The knife must be unsheathed when firing.
The hilt contains four barrels, split into two on each side by the blade, and one barrel holds one ammunition. This means that the total ammunition capacity of the QSB-11 is four. To reload, the operator must unscrew the rear cover and manually remove the shells from the back of the barrel.[3]
