Sig Sauer has received a $580 million contract to provide Modular Handgun Systems for the U.S. Army.

Under the agreement, the company will provide handguns, accessories and ammunition to replace the Beretta M9 currently in service with the branch. The M9 has been the standard sidearm of the U.S. Navy, U.S. Army, and U.S. Air Force since 1985.

The Modular Handgun Program was an open competition to replace the Beretta M9 as the standard sidearm. A Request for Proposals was posted in September 2015.

Bids were solicited online with nine received. The U.S. Department of Defense did not disclose where the work will be performed, but expects the work to be complete by Jan. 19, 2027.

The Army Contracting Command in New Jersey is listed as the contracting activity.
