Sauer P320 pistol was introduced in 2014. It is a further
development of the SIG Sauer P250. The pistol was aimed at a US Army requirement to
M9. The program was known as the XM17 Modular Handgun System. In 2017 the SIG
Sauer won against 8 other competitors to provide new pistols for the US
Air Force and US Army. Within the next 10 years the M9 pistols will
be gradually replaced by the P320, which will enter service as the
M17. It is expected that a contract for roughly 280 000 full-size
pistols will be awarded for the US Army, more than 200 000 for the
Air Force, Navy and Marines, plus perhaps as many as 10 000 compact
pistols. It is going to be the largest
pistol contract since 1985, when the US Army adopted the Beretta
92FS as the M9. The SIG Sauer
