FORT STEWART, Ga. (AP) — Firearms manufacturers are competing for a rare chance to sell the Army an easier-to-shoot handgun that can inflict more damage on enemies in a deal worth up to $580 million.

The Army wants to replace its M9, a 9mm semi-automatic handgun adopted during the Cold War. It was intended as a defensive weapon, a last-ditch option in close-quarters combat. The new gun also will replace the smaller M11.

Soldiers say they dislike the M9’s bulky grip. They want a gun capable of firing a bigger or harder-hitting bullet.

Army officials say the new gun must be adjustable and accommodate accessories common in the civilian market, such as swappable sights or lights.

The contract winner gets a tacit stamp of approval that could boost sales in other markets.
