(partial excerpt below)

The HS2000 (Hrvatski Samokres, English: Croatian pistol) is a series of semi-automatic pistols. Polymer-framed and striker-fired, the series is manufactured by HS Produkt (formerly I.M. Metal) in Karlovac, Croatia. In Europe, the pistols are marketed as the HS and XDM series, while in the United States, the pistols are sold as the Springfield Armory XD and XD-M series, respectively.

The HS2000 traces its roots back to a service pistol known as the PHP (Prvi Hrvatski Pistolj, English: first Croatian pistol), which was first produced in Croatia by privately-owned industrial parts firm I. M. Metal in 1991.[2] Designed by a team led by Marko Vuković, the PHP was considered to be a solid design, but early versions were plagued by quality issues, due in large part to the difficulties of manufacturing during the Yugoslav war.[3] Vuković's team continued to tweak and improve the design over the next decade, releasing the HS95 (Hrvatski Samokres or Croatian Pistol) in 1995, and the HS2000 in 1999. At the beginning of 2001, following the success of the HS2000 pistols on the world market, the company changed its name to HS Produkt.[4]

The HS2000 was adopted by the Croatian military and law enforcement as a standard issue sidearm. It was initially exported to the United States market by Intrac and distributed by HSAmerica, who sold the pistol in 9×19mm Parabellum (9mm) as the HS2000.[5] In 2002, Springfield Armory, Inc., negotiated licensing rights to the United States market, using XD (eXtreme Duty) branding. In 2013, HS Produkt began (via a wholesale distributor) to offer updated variants, branded as XDM,[a] in Europe.[6] As of March 2020, HS Produkt lists both HS series and XDM series pistols on its website,[7] corresponding to the XD and XD-M series, respectively, sold in the United States by Springfield Armory.
