Heckler & Koch MP5

The Heckler & Koch MP5 (from German: Maschinenpistole 5, meaning machine pistol 5) is a 9mm submachine gun of German design, developed in the 1960s by a team of engineers from the German small arms manufacturer Heckler & Koch GmbH (H&K) of Oberndorf am Neckar. There are over 100 variants of the MP5, including a semi-automatic version.

The MP5 is one of the most widely used submachine guns in the world, having been adopted by 40 nations and numerous military, law enforcement, intelligence, and security organizations. It is widely used by SWAT teams in North America.

In 1999, Heckler & Koch developed the Heckler & Koch UMP, the MP5's successor; both are available as of 2015.

History

Heckler & Koch, encouraged by the success of the G3 automatic rifle, developed a family of small arms consisting of four types of firearms all based on a common G3 design layout and operating principle. The first type was chambered for 7.62×51mm NATO, the second for the 7.62×39mm M43 round, the third for the intermediate 5.56×45mm NATO caliber, and the fourth type for the 9×19mm Parabellum pistol cartridge. The MP5 was created within the fourth group of firearms and was initially known as the HK54.

United States one-dollar bill

The United States one-dollar bill ($1) is a denomination of United States currency. The first U.S. President (1789–97), George Washington, painted by Gilbert Stuart, is currently featured on the obverse (front), and the Great Seal of the United States is featured on the reverse. The one-dollar bill has the oldest design of all U.S. currency currently being produced. The design seen today debuted in 1963 when it was first issued as a Federal Reserve Note (previously, one dollar bills were Silver Certificates).

The inclusion of the motto, "In God we Trust," on all currency was required by law in 1955, and first appeared on paper money in 1957.

An individual dollar bill is also less formally known as a one, a single, a buck, a bone, and a bill.

The Federal Reserve says the average life of a $1 bill in circulation is 5.9 years before it is replaced because of wear. Approximately 42% of all U.S. currency produced in 2009 were one-dollar bills.

Heckler & Koch VP9

The Heckler & Koch VP9 is a polymer-framed semi-automatic striker-fired handgun. It is known under the designation SFP9 in Europe.

History

According to the manufacturer, the pistol was under development for more than four years before its release in June 2014.

Design details

The VP9 is striker-fired, and features a Picatinny rail. The European version comes in two variants, designated SFP9-SF and SFP9-TR respectively. The latter features a heavier trigger pull and longer reset to accommodate German legislation on police handguns.

Controls on the VP9 are ambidextrous, achieved through a dual paddle-style magazine release on the trigger guard, and an extended slide release lever on the right side of the firearm.

The weapon sports a loaded chamber indicator in the form of the extractor protruding with a red mark when a round has been chambered. The position of the firing pin can be seen through a hole in the rear of the slide, serving as an indicator of whether the striker is cocked or not.

Heckler & Koch USP

The USP (Universelle Selbstladepistole or "universal self-loading pistol") is a semi-automatic pistol developed in Germany by Heckler & Koch GmbH (H&K) of Oberndorf am Neckar as a replacement for the P7 series of handguns.

History

Design work on a new family of pistols commenced in September 1989 focused primarily on the U.S. commercial and law enforcement markets. USP prototypes participated in rigorous testing alongside H&K's entry in the Offensive Handgun Weapon System (OHWS) program requested by the U.S. Special Operations Command (USSOCOM) and which would later result in the Mk 23 Mod 0. The USP prototypes were then refined in 1992, based on input from the OHWS trials, and the design was finalized in December of the same year. The USP was formally introduced in January 1993 with the USP40 model (the base version) chambered for the increasingly popular .40 S&W cartridge, followed soon by the USP9 (using the 9×19mm Parabellum cartridge), and in May 1995—the USP45 (caliber .45 ACP). In contrast to the ambitious and innovative P7, P9S, and VP70Z designs, the USP uses a more conventional Browning-style cam-locked action, similar to that used in the Hi-Power - but with a polymer frame.
