Firearms manufacturer SIG SAUER has been contracted to supply a new modular handgun system (MHS) for the US Army.

The army intends to replace its M9 service pistol with the SIG SAUER Model P320 polymer striker-fired pistol.

Under the contract, the company will deliver both full-size and compact P320s over the next ten years.

The pistols can be configured with silencers, as well as standard and extended-capacity magazines, the company stated.

US Army acquisition executive Steffanie Easter said: “By maximising full and open competition across our industry partners, we truly have optimised the private sector advancements in handguns, ammunition and magazines and the end result will ensure a decidedly superior weapon system for our warfighters.”

The P320 features interchangeable grip modules with adjustable frame sizes and calibres, including 9mm, .357SIG, .40S&W and .45ACP.

All pistols will be produced at the SIG SAUER's facilities in New Hampshire.

"The end result will ensure a decidedly superior weapon system for our warfighters."

According to SIG SAUER, P320 Full-Size striker-fired pistol features a full-size grip, full length slide, while the P320 Compact features a compact grip and compact slide.

Both versions of the pistol are offered with either contrast or SIGLITE Night Sights.

SIG SAUER recently expanded its Match Grade Elite Performance Ammunition line for rifles with the addition of 300 Win Mag open-tip-match (OTM) rounds.

The Match Grade Elite Performance Ammunition features a temperature-stable propellant that is said to deliver consistent muzzle velocity in all weather conditions.
