<P> On January 19 , 2017 , it was announced that the SIG Sauer P320 MHS variant had won the United States Military 's Modular Handgun System trials . The P320 will be known as the M17 ( full size ) and M18 ( compact ) in U.S. Military service . Though the pistol will remain chambered in 9 x 19mm Parabellum rather than a larger caliber , the contract allows the Army and other services to procure Sig Sauer 's proposed XM1152 Full Metal Jacket and XM1153 Special Purpose ammunition . The ammunition chosen to go with the pistol is a `` Winchester jacketed hollow point '' round . </P>
