The Sig Sauer P320 pistol has been chosen as the winner of the Modular Handgun System (MHS) competition to replace the Beretta M9 as the service pistol of the U.S. Army.

The U.S. Army on Thursday awarded Sig Sauer a contract worth $580 million to make the service’s next service pistol.

Sig Sauer beat out Glock Inc., FN America and Beretta USA, the maker of the current M9 9mm service pistol.

“I am tremendously proud of the Modular Handgun System team,” Army Acquisition Executive Steffanie Easter said in a Jan.19 press announcement. “By maximizing full and open competition across our industry partners, we have optimized private sector advancements in handguns, ammunition and magazines, and the end result will ensure a decidedly superior weapon system for our warfighters.”

The Army did not offer any details about what caliber the new Sig Sauer pistol will be.

I’m going to be very surprised if the Army moves away from 9mm, but suspect we’re going to see upgraded ammunition in the caliber.
