The SIG Sauer M17 and M18 are service pistols derived from the SIG Sauer P320 in use with the United States Armed Forces. On January 19, 2017, the United States Army announced that a customized version of SIG Sauer's P320 had won the Army's XM17 Modular Handgun System competition. The full-sized model was designated the M17, and the shorter length carry model, the M18.^[4] The guns have subsequently been adopted by the Army, Navy, Marine Corps, Air Force, and Space Force. The Coast Guard is the only military branch that will not be receiving the M17 and M18, they will be replacing their SIG Sauer P229R DAK with the Glock 19 Gen5 MOS.^[5][6][7] The M17 and M18 will be replacing the Beretta M9, as well as several other handguns across five of the six service branches. There are two color variants, coyote brown and black, for both the M17 and M18, though almost all have been produced in coyote brown.
