Per the included certificate, this pistol was part of the initial deployment of the U.S. M17 MHS Pistol in American service. A variant of the SIG 320 modular pistol, the M17 integrates an ambidextrous thumb safety to the modular fire control unit which is fitted in a "M" size grip unit, with illuminated night sights, optics mounting point on the slide, and coyote brown metal and polymer finish. The shipping box is a numbered match to the pistol and identifies it as "UDM17-9-SURPLUS", and contains two extra magazines one of which is marked with the number "2", cable lock, and papers.
