context_page_description: The USP is a semi-automatic pistol developed in Germany by Heckler & Koch GmbH of Oberndorf am Neckar as a replacement for the P7 series of handguns.
context_section_description: The USP Expert (9 mm Parabellum, .40 S&W, .45 ACP), was introduced in 1998, and includes all the features of the Tactical, with the exception of the threaded barrel.  The USP Expert also retains the USP match trigger.  It also features an extended steel slide, mostly hiding the longer O-ring barrel. The extended slide adds weight to help reduce muzzle flip and felt recoil. The Expert has adjustable target sights similar to the USP Match, Elite, and Tactical, however the slide the rear sight seat is milled lower. The Expert may be used with an extended magazine well, or jet funnel, in 9 mm and .40 S&W calibers. These are used with larger-capacity magazines. The Jet Funnel magazines are clear plastic, and hold 18 rounds for 9mm, and 16 rounds for .40 S&W. The jet funnel magazine can be used without the jet funnel installed, and will protrude slightly from the bottom of the magazine well.  However, after the jet funnel is installed, only jet funnel magazines can be used. The standard USP magazines are too short to lock in place. The bobbed hammer was a factory option for the Expert if it was to be used in IPSC for the Standard Division because the original version "in its ready condition" did not fit the box for Standard division in IPSC.
