In 1998, the H&K USP Compact with the LEM trigger action, in .40 S&W, was adopted by the United States Immigration and Naturalization Service as the duty sidearm for its Special Agents and plainclothes officers. In 2004, after the INS's criminal investigations branch merged with the U.S. Customs Service's Office of Investigations into the U.S. Department of Homeland Security's Homeland Security Investigations, the former INS Special Agents continued to carry the USP Compact. New duty pistols, the SIG Sauer Model P229 DAK, in .40 S&W, were eventually issued to the HSI Special Agents after new pistol contracts were awarded by the DHS.
