USP (dePistole) is HK's first pistol designed specifically for the US market. Its design principles are based on the user requirements of US civilians, law enforcement agencies and military departments. HK originally tried to use the advantages of guns successfully developed in the past as a basis for future development.
Reference for the development of pistols, among which the innovative pistols developed by HK in the past include the P7 with a unique trigger structure, the P9S and VP70Z with pure double-action trigger mode, etc. After HK Company successfully developed the USP pistol in 1993, it also represented the first time that HK absorbed
Many traditional pistol design elements, such as John Browning's M1911. The firearm is mainly designed based on two principles, one is polymer materials as raw materials, and the other is the creation of paradigm pistols. The USP uses more Browning pistols
The design is similar to Browning's "HiPower", and the USP has a fixed lock and ready mode.
USP was first demonstrated to the public at the 1993 SHOT Show in Houston, and in the same year, USP began production.
USP can fire the most powerful 9mm bullets, because USP is originally designed and manufactured according to the specifications of firing .40 bullets. There are 9 models of USP regardless of which caliber. The difference between different models is only the trigger method and control lever function.
Different from the location, this gives users a larger choice space, and each model can be modified to another model at will. Although USP is more expensive, it has excellent accuracy, strong durability, and ergonomic efficiency.
It is well designed and the recoil is easy to control. In particular, its grip design is excellent, allowing people to hold it tightly and straight naturally. It has excellent directivity when shooting by feel. It is better than the Glock pistol in terms of directivity and grip comfort.
The USP initially had only two calibers: 9mm and .40S&W. Although these two models are quite popular, many Americans have always been fond of the .45 caliber. At that time, the US military chose the 9mm-firing Bereda 92F pistol as its
After becoming the standard pistol, the Colt M1911 pistol series fired .45ACP (Automatic Colt Pistol) bullets are still widely used by civilians or various military departments and law enforcement agencies. Therefore, HK Company designed the USP fired .45ACP bullets, and in May 1995
Launched on the market in March.
As the size and power of fired bullets have increased, some parts need to be strengthened, and the overall dimensions have also changed. In order to prevent the grip from becoming too large and difficult to hold, USP's original plastic magazine was changed to steel bullets.
The magazine has a capacity of 12 rounds, and the civilian-type magazine has a capacity of 10 rounds. Many original USP parts and accessories can still be used universally, such as UTL, etc.
USP's sliding sleeve is machined from a single piece of high-carbon steel using a machine tool. The surface is treated with high temperature and nitrogen. This secondary hardening treatment can enhance the wear resistance of the movable components. The surface of the sliding sleeve has been treated with special anti-rust treatment.
, its anti-rust layer penetrates deep into the metal surface, making the slide sleeve more rust-proof. The barrel is made of chromium steel through cold forging (cold forging will not change the direction of the metal crystal), and its barrel material is similar to
The barrels are of the same grade.
The USP gun body is made of polymer plastic. In order to avoid uneven weight distribution between the slide and the gun body, the gun body is lined with a steel frame to lower the center of gravity of the pistol and increase the stability when shooting. For this reason, the USP pistol has another
A special design: a double repeating spring device. Since the bullets used in the original USP pistol design were 9mm Luger and .40S&W, this double spring can offset the strong recoil of these two bullets to increase the USP rapidity.
Accuracy when shooting.
USP's firing pin safety and hammer safety are modular, and the trigger group also has multiple functions, which can be selected according to the shooter's habits. When designing, USP absorbed the advantages of the Grack pistol series and the SIG pistol series.
, such as the use of polymer plastic, the configuration of the slide, and the locking mechanism. The USP also pioneered the multi-purpose groove on the front edge of the bow guard, which can be attached with a special laser calibration sight or a bright flashlight, which makes the USP pistol
Become the first gun with complete accessories to perform anti-terrorism and special missions.
USP type
USP Compact (USPCompact)
It appeared on the market after the promulgation of the "Assault Weapons Prohibition Act" in the United States in 1994. This regulation limits the magazine capacity of civilian guns to no more than 10 rounds. But the biggest change in the USP compact is not just the reduction in magazine capacity;
The size of the entire gun has been reduced, and even the hammer has been reduced to be hidden in the slide, making it very suitable for plainclothes agents to hide on their bodies.
USPMatch (competitive type)
Compared with other competition pistols, the changes of the competition pistol are relatively simple. They just extend the barrel of the original USP standard pistol and use the original UTL mounting rail to fix a muzzle brake. There is an inconspicuous one behind the trigger.
The nail-shaped object is a device used to adjust the trigger force. In addition, the front sight of the USPMatch has also been changed to be adjustable. The USPMatch can use standard large-capacity magazines, but only 10-round magazines can be used in the United States. USP
Although it was not developed for the German military, due to its excellent and reliable performance, it coincided with the major re-equipment of the Bundeswehr. Therefore, HK Company developed the P8 military pistol for the German army based on 9mmUSP. In addition to sniper rifles, assault rifles
, from light machine guns to pistols, the German army has replaced them with HK's new products from the 1990s.
USP Expert (USPExpert)
It first appeared in the European IPSC shooting competition in 1998, and later appeared in the United States as a .45-caliber model. The USP Expert model is the same as the USP Competition model, with an extended barrel and adjustable front sight.
In Europe, USP Expert magazines are large-capacity magazines, while in the United States they are limited to 10 rounds or less.
USPElite Expert (USP Elite)
The competition pistol released by HK Company in early 2000 currently only has prototype guns, with calibers of 9mm and .45, and magazine capacities of 18 and 12 rounds respectively. It is expected that USPElite will mainly target European customers, not the United States. From
In terms of appearance, USPElite is slightly longer than USPExpert, and the cutting under the muzzle is arc-shaped, so it is easy to distinguish. The MK23SOCOM developed by HK Company to meet the needs of the US Special Operations Command for an "offensive" pistol is excellent in accuracy and reliability.
It has been well received, but the size and weight are too large, and it is not easy to control if it is not held with both hands. Because HK company has developed the USPTACTICAL (USP tactical type), which fully meets military standards, but is lighter in weight.
"Offensive" pistol.
USPCustomSport
The competition pistol looks like the regular USP standard model, but uses a competition-grade barrel, an adjustable rear sight, a magazine bottom plate that extends forward, and an adjustable trigger force.
